(ANNOUNCER)>> TODAY ON
ENGINE POWER WE'LL FINISH OFF THE CLASSIC FORD
FLATHEAD WE STARTED A WHILE BACK FROM ASSEMBLY TO THE
DYNO WITH THE HELP OF ANOTHER LEGEND, THE FAMOUS
ENGINE BUILDER KEITH DORTON.
(MIKE)>> A WHILE BACK WE TOOK A CLOSER LOOK AT THE ENGINE THAT LAUNCHED AN ENTIRE LIFE STYLE AND
INDUSTRY BASED ON POWER AND SPEED, THE FORD FLATHEAD. A SIMPLISTIC VEIGHT WITH ROOM FOR IMPROVEMENT, AND IT DIDN'T TAKE LONG TO FIND IT. IT WAS THEN WHEN EDELBROCK MARKETED HIS FIRST HIGH PERFORMANCE INTAKE MANIFOLD, WITH A CYLINDER HEAD SOON TO FOLLOW. AND HE WASN'T ALONE. GO FAST PARTS WERE POPPING UP EVERYWHERE. A NEW PURPOSE FOR THE FLATTY WAS WELL ON ITS WAY. WE FOUND OURS IN A JUNKYARD INTACT. THE CASTING TELLS IT'S FROM THE MID-'50'S, AND THE RUST CONFIRMS IT. THIS THING IS LOCKED UP SOLID. A SHORT SOAK FREED UP SOME PISTONS BUT THE REST PUT UP A BATTLE. THE BLOCK HAD BEEN PREVIOUSLY BORED AND APPEARED SOLID, BUT ONLY A TRIP TO A MACHINE SHOP CAN CONFIRM IT. AFTER A SHOT PEEN AND SOME MAGNAFLUXING WE FOUND
SEVERAL SMALL CRACKS BETWEEN SOME WATER JACKETS AND THE BOLT HOLES. FORTUNATELY AN EASY FIX, BY DRILLING OUT THE ORIGINAL HOLES AND DRIVING IN A LUBED INSERT WITH A BOLT. ONCE SEATED AND THE BOLT REMOVED, THE NEW THREAD STOPS THE CRACK, GIVING THE NEW STUDS A STRONGER CLAMPING AREA. THE CYLINDERS CLEANED UP WELL, NO SLEEVES NEEDED. SO WE HAVE THE GREEN LIGHT TO CONTINUE. THE VALVE SEATS WERE NEXT AND THE OLD ONES PUT UP A FIGHT AS WELL. WITH A PILOT IN PLACE THE NEW ONES ARE DRIVEN IN. WE GAVE THE EXHAUST A STANDARD THREE ANGLE VALVE JOB, BUT THE INTAKES GOT OPENED UP A LITTLE, DESHROUDED, THEN A THREE ANGLE CUT AS WELL. AND THAT'S AS FAR AS TIME ALLOWED US TO GO. ANOTHER PROJECT CALLED US AWAY. SO WE CALLED ON AN OLD FRIEND TO TAKE OVER. HE GREW UP IN THE HEART OF NASCAR COUNTRY WITH AN EARLY PASSION FOR SPEED.
WHILE HE ENJOYED THE THRILL OF DRIVING RACE CARS, KEITH DORTON LOVED THE CHALLENGE OF MAKING POWER FOR THEM. IT CONSUMED HIS IMAGINATION AND CREATIVITY. HIS ENGINES HAVE BEEN WINNING RACES FOR FIVE DECADES. NOW IN THE 1960'S HIS CYLINDER HEAD MAKING MAGIC PROVIDED THE WINNING EDGE FOR LEGENDS LIKE JUNIOR JOHNSON, BOBBY ALLISON, AND CALE YARBOROUGH. HE MAY BE THE ONLY ENGINE BUILDER IN HISTORY TO HAVE WORKED FOR THREE GENERATIONS OF EARNHARDTS.
ALTHOUGH STILL INVOLVED IN CIRCLE TRACK COMPETITION, KEITH'S BUILT ENGINES FOR 19 RECORD BREAKING CARS AT THE BONNEVILLE SALT FLATS, AND HE'S NOT DONE YET. WORKING WITH HIS SON JEFF, KEITH'S COMPANY, AUTOMOTIVE SPECIALISTS, HAS BROADENED ITS HORSEPOWER HORIZONS. WHILE PRIORITY REMAINS ON RACE ENGINES, THEY'LL ALSO FOCUS ON BUILDING CUSTOM STREETABLE ENGINES FOR ALL SORTS OF HOT RODS AND CLASSICS.
(KEITH)>> YOU'RE GONNA SPEND A LOT OF MONEY AND GOT A TOTALLY UNIQUE CHASSIS AND BODY COMBINATION, WHY NOT PUT A UNIQUE ENGINE COMBINATION. IT'S PRETTY EASY TO MAKE HORSEPOWER, BUT WHAT WE HAVE TO DO FOR THIS APPLICATION IS MAKE DRIVABLE POWER.
(MIKE)>> AND THAT'S WHY WE CALLED KEITH. YOU'LL SEE HOW HE DOES IT AFTER THE BREAK.
(ANNOUNCER)>> UP NEXT, KEITH IS HERE, LET THE BUILD BEGIN!
(MIKE)>> WE'RE BACK AND SO IS THE FLATHEAD, ALONG WITH LEGENDARY ENGINE BUILDER KEITH DORTON. HE ALSO BROUGHT HIS PASSION.
(KEITH)>> YOU KNOW THE COOLEST SOUNDING ENGINES YOU'VE EVER HEARD HAVE A UNIQUE SOUND,
AND THEY RUN SO SMOOTH. AND YOU KNOW, IN A STOCK FORM THEY WERE JUST AS QUIET AS A CADILLAC ENGINE. IT WAS GOOD TO FIND A BLOCK THAT WAS IN AS GOOD A CONDITION AS THIS ONE IS, EVEN THOUGH IT HAD SOME CRACKS IN IT THAT ARE COMMON WITH THE FLATHEADS. BUT THIS ONE'S ABOUT AS GOOD AS YOU'RE GONNA FIND NOW. ALL THAT WE HAD TO DO AT THE SHOP, AND IT WASN'T A MUST, WAS WE DID THE RELIEVING THE BLOCK. WHICH THE AREA BETWEEN THE VALVES AND THE CYLINDER, WE DROPPED IT ABOUT 80 TO 90 THOUSANDTHS TO INCREASE THE
AIR FLOW FROM THE VALVES TO THIS CYLINDER, WHICH IS PART OF THE COMBUSTION CHAMBER. I REALLY WANT TO START COLLECTING SOME PARTS MYSELF
AND YOU KNOW, WANT TO BUILD ANOTHER HOT ROD ONE DAY. AND IT'LL HAVE A FLATHEAD IN IT WHEN I DO.
(MIKE)>> THE GOAL FOR THIS ENGINE IS PRETTY SIMPLE. WE WANT A SMOOTH RUNNING USER FRIENDLY ENGINE THAT DOESN'T REQUIRE A LOT OF MAINTENANCE. NOW FOR THAT WE'RE USING PARTS FROM SEVERAL
MANUFACTURERS THAT HAVE BEEN IN THE PERFORMANCE WORLD FOR YEARS. LIKE SCAT WITH THEIR POPULAR FORD FLATHEAD ROTATING ASSEMBLY. NOW THIS IS THEIR CAST CRANK WITH A FOUR-250 STROKE THAT HAS BEEN INTERNALLY BALANCED WITH THE REST OF THE KIT. NOW ATTACHED TO IT ARE SET OF HBEAM SEVEN INCH RODS THAT ARE HELD TOGETHER WITH ARP 8740 ROD BOLTS. NOW THE PISTONS HAVE A COOL LITTLE STORY IN THEMSELVES. LIKE THE ORIGINALS WE BUSTED OUT OF THE BLOCK, THESE HAVE A SLIGHT DOME. NOW IN THE FLATHEAD WORLD THEY'RE CONSIDERED A FLAT TOP. NOW AS FAR AS A HORSEPOWER GOAL, WE'RE GONNA LET THE DYNO DECIDE CAUSE WE JUST DON'T KNOW. THE FIRST PART OF THE BUILD WILL BE THE BOTTOM END. NOW A SET OF CLEVITE BEARINGS WILL FILL THE FLATHEAD'S THREE MAIN JOURNALS. ROYAL PURPLE ASSEMBLY LUBE WILL PROTECT THE BEARINGS AS WE ASSEMBLE IT. NOW THE CRANK SHAFT IS SCAT'S 9,000 SERIES MADE FOR THE STREET AND STRIP. IT WILL GIVE OUR FLATHEAD 304 CUBIC INCHES. NEXT UP ARE THE ORIGINAL MAIN CAPS.
NOW THEY'RE FILLED WITH THE OTHER HALVES OF THE CLEVITE BEARINGS.
ARP BOLTS WILL ANCHOR THEM IN.
WITH ARP'S ULTRA TORQUE ON THE BOLTS WE CAN TORQUE THE FIRST TWO CAPS TO 40 FOOT POUNDS. FORCING THE CRANK TOWARDS THE FRONT OF THE ENGINE WILL ALIGN THE TWO HALVES OF THE THRUST BEARING, WHICH IS AT THE REAR. NOW TORQUE THAT CAP TO 40 FOOT POUNDS. SET UP THE MAGNETIC BASE AND DIAL GAUGE ON THE CRANK
SNOUT AND WITH THE READING AT ZERO WE'LL ROCK THE CRANK FROM FRONT TO BACK TO CHECK THE THRUST CLEARANCE. RIGHT AT SIX, WHICH IS IN SPEC. NOW TORQUE ALL THE CAPS TO THE FINAL VALUE OF 70 FOOT POUNDS.
BEFORE WE MOVE ON A MASKING JOB AND SOME OLD TINS FROM THE ORIGINAL ENGINE WILL GIVE US THE COVER WE NEED TO ADD SOME COLOR.
HERE'S A PRELUDE OF THINGS TO COME. IT SPEAKS FOR ITSELF BUT WE'LL TELL YOU MORE ABOUT IT ON THE DYNO. DUPLICOLOR'S GRAY ENGINE PRIMER AND RED ENGINE
PAINT WILL GIVE THE FLATTY A SLICK LOOK. MOVING FORWARD WITH THIS BUILD REQUIRES THE NUMBER ONE PISTON TO BE IN PLACE. THE SCAT ROD IS HELD TO THE ROSS FORGED PISTON WITH A FLOATING PIN. THE SPIRAL LOCKS WILL KEEP IT IN PLACE.
GAPPING THE RINGS IS A MUST. KEITH IS USING OUR GOODSON FILER TO OPEN THE GAPS, WHICH WILL AVOID THEM FROM TOUCHING WHEN THE ENGINE GETS UP TO TEMPERATURE, WHICH WOULD LEAD TO A MAJOR FAILURE. THE RING PACK IS FROM TOTAL SEAL, THE BALANCING ACT IS FROM EXPERIENCE.
(KEITH)>> YOU KNOW I WAS THE ONLY REAL GEARHEAD IN MY CLASS WHEN I WENT TO SCHOOL. OF COURSE THAT MEANT I ALWAYS HAD TO FIX THE TEACHERS CARS, BUT MAYBE THAT'S THE ONLY WAY I PASSED TOO.
(MIKE)>> WITH ASSEMBLY LUBE IN PLACE AND THE PISTON OILED, WE CAN FILL THE THREE POINT THREESEVENFIVE INCH BORE. NOW THE ROD BEARING IS FROM A 327 SMALL BLOCK CHEVY THAT HAD BEEN NARROWED AND CHAMFERED TO THE FLATHEAD'S ROD JOURNAL WIDTH. NEXT UP IS THE ISKY FLAT TAPPET CAM SHAFT THAT STILL HOLDS THE NAME THREE QUARTER RACE CAM. NOW IT'S DESIGNED FOR MILD STREET AND GOOD LOW SPEED POWER. LIFT IS A SINGLE PATTERN AT 364 ON THE
INTAKE AND EXHAUST. THESE ISKY LIFTERS HAVE DEEP GROOVES IN THEIR BODY TO HOLD OIL AND LUBRICATE THE LIFTER BORE AS
THEY MOVE UP AND DOWN. THE SMALL NUT IS THE ADJUSTER TO SET THE VALVE LASH. BACK IN THE DAY ADJUSTABLE LIFTERS WERE NOT AVAILABLE. SO TO GET THE VALVE'S LASH, GRINDING ON THE VALVE'S STEM
OR ALTERING THE VALVE'S SEAT WAS THE ANSWER. NOW THE VALVE ASSEMBLIES CAN BE PUT TOGETHER. FIRST APPLY ASSEMBLY LUBE ON THE VALVE STEM. THEN THE VALVE GUIDE CAN GO ON FOLLOWED BY A SHIM, THE VALVE SPRING, RETAINER, AND FINALLY THE LOCKS. NOW IT GOES INTO THE BLOCK AS AN ASSEMBLY. THE INTAKE GOES TOGETHER THE SAME WAY BUT USES A SEAL ON THE GUIDE. THE NEXT STEP CAN BE TRICKY BUT WE HAVE THE RIGHT TOOL, SO IT SHOULD BE A BREEZE. BY USING A VALVE GUIDE TOOL SPECIFIC TO THE FLATHEAD, WE CAN PULL THE GUIDES DOWN AND INSTALL THE RETAINERS WITH A PAIR OF NEEDLE NOSE PLIERS. WITH THE EXHAUST VALVE JUST STARTING TO OPEN, USING A
FEELER GAUGE CHECK THE LASH BETWEEN THE LIFTER AND THE VALVE TIP. WE HAVE 12 THOUSANDTHS, WHICH IS A LITTLE TIGHT. NOW TO MAKE AND ADJUSTMENT THE LIFTER NEEDS TO BE MOVED UP AND A SMALL ALLEN SOCKET PLACED THROUGH THIS HOLE, WHICH KEEPS THE LIFTER FROM ROTATING.
USING A SEVENSIXTEENTHS WRENCH, THE ADJUSTOR IS TURNED IN TO OPEN THE LASH. NOW ROTATE THE ENGINE AGAIN SO THE EXHAUST VALVE STARTS
TO OPEN, AND CHECK THE LASH, WHICH IS RIGHT ON THE MONEY AT 14 THOUSANDTHS. SO FAR THIS BUILD IS MOVING VERY SMOOTH. MORE TO COME AFTER THE BREAK.
(ANNOUNCER)>> SO WHO'S THE COOLEST, THE FLATHEAD OR KEITH? MORE TO COME!
(MIKE)>> AT THIS POINT THE VALVES ARE IN AND LASHED ON THIS 1950'S FORD FLATHEAD. SO WE'LL LOCK THE CAM IN PLACE WITH THE ORIGINAL TIMING COVER, DRESSED WITH A NEW CRANK SEAL, SILICONE ON THE MATING SURFACE, AND A SMALL AMOUNT OF EXTREME PRESSURE LUBE WHERE THE NOSE OF THE CAM CONTACTS THE THRUST SURFACE OF THE COVER. WITH THE REMAINING PISTONS IN PLACE AND THE CAPS TORQUED TO 50 FOOT POUNDS, ALL THE INTERNAL ARE DONE. AND TO CONFIRM CAM SPECS, KEITH ALWAYS TAKES TIME FOR THE DEGREE WHEEL. NOW WE CAN INSTALL THE ARP HEAD STUDS INTO THE BLOCK. THEY WILL GIVE US THE EXTRA CLAMPING FORCE NEEDED TO
SEAL THE FLATTY'S HEADS. TO CONTROL ALL THE CRANK SHAFT VIBRATION, NOT JUST THAT IN A LIMITED FREQUENCY RANGE, WE'RE USING A FLUID DAMPER BALANCER ON THIS FLATHEAD. NOW THIS THING IS CONSTRUCTED OF ONLY THREE PIECES, THE HUB, A LASER WELDED OUTER SHELF, AND INSIDE IS A HIGHLY VISCOUS SILICONE FLUID THAT ACTUALLY ABSORBS ALL THAT VIBRATION. PLUS IT'S SFI APPROVED AND WE'RE READY TO PUT IT ON. IT REDUCES WEAR ON THE MAIN BEARINGS AND TIMING GEAR, HAS A SIX INCH DIAMETER AND IS MADE TO RUN VBELTS. NOW IT'LL REST AGAINST A SPACER THAT RETAINS THE OIL SLINGER. SUMMIT RACING SUPPLIED THE MELING STANDARD VOLUME OIL PUMP FOR THIS BUILD. IT DOES NOT USE A GASKET AND IS HELP IN PLACE WITH ONE FIVESIXTEENTHS BOLT. THE NEXT TWO PARTS WERE HARD TO FIND UNTIL WE FOUND THIS GUY, HAL FROM HAL'S GARAGE IN FAYETTE, OHIO.
NOW HE'S A WELL KNOWN GO TO SOURCE FOR OLD FLATHEAD PARTS. IF YOU WANT TO TAKE A TRIP BACK IN AUTOMOTIVE TIME, GIVE HIS LITTLE GARAGE A VISIT. THE OIL PUMP PICK UP IS AN ORIGINAL
PULLED BY HAL HIMSELF. IT CAME TO US WITH A MATCHING PAN THAT WAS IN AWESOME SHAPE FOR BEING OVER 61 YEARS OLD.
WITH THE SEALS INSTALLED WE CAN DROP THE PAN ON FEL PRO GASKETS AND WE'RE DONE WITH THE BOTTOM END. COPPER FEL PRO HEAD GASKETS ARE NEXT. NOW IT'S RECOMMENDED TO USE A SEALER LIKE VHT'S COPPER GASKETS SEALANT ON BOTH SIDES TO IMPROVE THEIR SEALING CHARACTERISTICS. GENTLY WORK THE GASKET OVER THE STUDS KEEPING IT EVEN AS IT GOES DOWN. VIC EDELBROCK SENIOR DESIGNED THE FIRST ALUMINUM PERFORMANCE FLATHEAD CYLINDER HEAD BACK IN 1938. NOW FROM THAT POINT ON PRODUCTION NEVER ENDED.
NOW THIS IS THE '49 THROUGH '53 VERSION, AND IT GOT ITS
NAME FROM THE THIN DESIGN. NOW UNDERNEATH THE COMBUSTION CHAMBER LOOKS SMALL BUT IT'S ACTUALLY 65cc. THEY'RE RIBBED INTERNALLY AND EXTERNALLY FOR STRENGTH, AND HAVE LARGE WATER JACKETS FOR BETTER COOLING. TO PROTECT THE SHINY FINISH OF THE NUT I'M LAYING A PIECE OF TISSUE OVER THEM, THEN PLACING THE SOCKET OVER IT. THIS WILL HELP AVOID SCARING TO THE HEX
PORTION OF THE NUT.
BOTH HEADS WILL BE TORQUED IN SEQUENCE TO 60 FOOT POUNDS. AND FOR THE FINAL TIME HERE'S EDELBROCK'S VINTAGE TRIPOWER INTAKE SETUP, AND IT'S NOT JUST FOR SHOW.
(KEITH)>> I THINK IT'S GREAT THAT YOU CAN BOLT THESE CARBS ON RIGHT OUT OF THE BOX.
GET YOUR RESULTS, WHICH I'M SURE WE'RE GONNA GET HERE.
THE MANIFOLD LOOKS SO COOL TOO.
(MIKE)>> FOR SPARK A MALLORY UNILITE ELECTRONIC DISTRIBUTOR, A HUGE LEAP IN TECHNOLOGY FROM THE '50'S. NEW HIGH FLOW WATER PUMPS ARE NEXT, AND THESE WILL BE THE LAST PARTS KEITH INSTALLS FOR US.
(KEITH)>> WE'VE GOT TO PUT SOME FUEL LINES ON IT, OR
YOU DO, CAUSE I'VE GOT TO GET BACK AND GET TO WORK. WE'VE BEEN GONE LONG ENOUGH.
(MIKE)>> KEITH DID WHAT HE CAME TO DO, REVIVING AN IMPORTANT PIECE OF HISTORY.
(KEITH)>> REALLY A FUN PROJECT TO COME BACK AND
WORK ON SOMETHING THIS OLD. AND I'M VERY CONFIDENT THAT WE'RE GONNA GET SOME GOOD RESULTS OUT OF IT.
(MIKE)>> AND IF KEITH SAYS SO, SO IT SHALL BE.
(ANNOUNCER)>> YOU HEARD THE MAN, UP NEXT, DYNO TIME!
(MIKE)>> WE'RE BACK AND READY FOR THE DYNO, BUT AS IT TURNS OUT I'M NOT ALONE AFTER ALL. ANOTHER HIGH PROFILE ENGINE BUILDER, PAT TOPOLINKSKI, CAME BY TO WATCH THE RUN, BUT I'M PUTTING
HIM TO WORK INSTEAD.
(PAT)>> THEY'RE EASY TO MODIFY, EASY TO WORK ON. I LOVE THEM TO TELL YOU THE TRUTH.
(MIKE)>> YOU MAY RECOGNIZE HIS FACE, HE HELPED US WITH OUR DRIVEWAY RESCUE SEGMENTS IN THE PAST. BUT HIS CLAIM TO FAME IS BEING A TEAM MEMBER OF KB RACING'S MULTICHAMPIONSHIP WINNING NHRA PRO STOCK TEAM, WHERE HIS DUTIES INCLUDED CLUTCH AND TRANSMISSION SETUP, ENGINE DEVELOPMENT, AND ANY THING ELSE HE COULD GET HIS HANDS ON.
AND TODAY IT'S A FLATHEAD.
(PAT)>> YOU KNOW I CAME HERE TO WATCH, BUT I'M A HORRIBLE SPECTATOR. AND IF YOU DIDN'T COME HERE TO PITCH IN, YOU
SHOULDN'T BE HERE ANYWAY.
(MIKE)>> PATRIOT TIGHT TUCK STREET ROD HEADERS WILL DIRECT THE EXHAUST GASES OUT OF THE ENGINE. NOW TO SET THE BELT TENSION WE'RE USING EDELBROCK'S OFFSET ALTERNATOR BRACKET AND TOPPING IT OFF WITH POWERMASTER'S POWER GEN 90 AMP 12 VOLT ALTERNATOR. EDELBROCK'S TRIPLE DEUCE FUEL LINE KIT WILL MAKE THE PLUMBING SUPER EASY. NOW THE 94 TWO BARREL CARBS WERE BORN IN 1938 AND
PRODUCTION STOPPED IN '57. IN 2010 EDELBROCK MADE THEM AVAILABLE ONCE AGAIN TO FEED NOSTALGIA ENGINES LIKE THIS. REMEMBER THAT OIL PUMP PICK UP WE INSTALLED EARLIER? WELL THIS SCREEN IS THE ONLY FILTRATION A FLATHEAD EVER GOT, WHICH ISN'T GOOD ENOUGH. SO KEITH MADE SOME MODIFICATIONS TO THE BACK SIDE OF THE BLOCK. NOW THAT'S GONNA LET US RUN A REMOTE OIL FILTER. NOW THE BLUE FITTING IS PRESSURE INTO IT AND THE BLACK FITTING IS PRESSURE BACK INTO THE ENGINE. FROM THE MILODON REMOTE FILTER ADAPTER WE RAN THE TWO LINES TO THE FITTINGS AT THE BACK OF THE ENGINE, AND ONE MORE LINE TO MONITOR PRESSURE AT THE DYNO CONSOLE. NOW THE ALL IMPORTANT FILTER. WE'LL PRIME IT WITH FIVE AND A HALF QUARTS OF ROYAL PURPLE BREAK IN OIL. A QUICK CHECK FOR LEAKS, PRESSURIZE THE FUEL SYSTEM
TO FILL UP THE BOWLS. KEITH, HEY, HOW ARE YOU. I MADE A COURTESY CALL TO LET KEITH KNOW
WHAT WAS GOING ON. I'LL CALL YOU THIS AFTERNOON.
(PAT)>> WHOA!
(MIKE)>> WOW!
(PAT)>> ALRIGHT!
(MIKE)>> THAT TIMING WAS DEAD ON. OUR DISTRIBUTOR HAS 14 DEGREES OF MECHANICAL ADVANCE BUILT IN. TO START WE'LL RUN 24 DEGREES OF TOTAL TIMING AND ADVANCE IT FROM THERE. NOW WE CAN BREAK IN THE CAM SHAFT BY RUNNING THE ENGINE FROM 15 TO 2,200 RPM FOR 20 MINUTES. WITH GREAT OIL PRESSURE, THE RECOMMENDED FUEL PRESSURE, WE'RE READY TO ADJUST THE CARBURETORS. WE'RE GONNA SET THE THROTTLE BLADES ON EACH CARBURETOR SO THEY OPEN EVENLY. THEN WE NEED TO SET IT UP SO THEY'RE SYNC'ED TOGETHER BASED OFF OF VACUUM. NOW FOR THAT WE'LL GET HELP FROM THE UNISON TOOL FROM EDELBROCK. NOW IT'S TIME TO FIRE IT UP.
WE'LL GET THE ENGINE TO IDLE BY OPENING THE THROTTLE BLADES OF EACH CARB EVENLY. NOW PLACE THE UNISON ON THE CENTER CARB AND TURN THE AIR FLOW CONTROL TO GET THE RED INDICATOR IN THE CENTER OF THE TUBE. WITHOUT CHANGING THE AIR CONTROL VALVE, PLACE IT ON THE OTHER CARBS AND ADJUST THE IDLE CONTROL SCREW TO MAKE THE RED INDICATOR REACH THE SAME LOCATION
AS THE CENTER CARB. NOW WE CAN REATTACH THE LINKAGE AND CHASE DOWN SOME OLD SCHOOL GRUNT. GOT YOUR SEATBELT ON AND YOUR HELMET STRAPPED?
(PAT)>> I'M READY! LET HER RIP TATER CHIP! [engine revving]
(MIKE)>> 156, 247.
(PAT)>> AWESOME, I LIKE IT. LETS THROW SOME TIMING AT IT AND SEE HOW IT LIKES IT.
LETS SNEAK IT UP TO ABOUT 26. [ engine revving ]
(MIKE)>> 159, 264.
(PAT)>> NICE!
(MIKE)>> THAT'S NICE, NICE SMOOTH GRAPH TOO,
AND IT'S STILL CLIMBING. TO FIND ITS THRESHOLD WE TRIED 28 DEGREES AND
LOST A LITTLE OF BOTH. 157, 253, BUT STILL COOL FOR BEING OVER 60 YEARS OLD.
(PAT)>> SEE THE COOLNESS FACTOR ON THIS ONE IS OFF THE CHARTS.
(MIKE)>> SO IT'S BACK TO 26 DEGREES FOR ONE LAST PULL. WE'LL CLAIM VICTORY AT 159 HORSEPOWER AND 257 FOOT POUNDS OF TORQUE. YOU GLAD YOU CAME BY?
(PAT)>> I'M GLAD I CAME BY, I'M GLAD I GOT TO BE ABLE TO HELP WITH IT. THIS IS ULTRA COOL. IT'S A GREAT LITTLE ENGINE, IT LOOKS GREAT.
(MIKE)>> WE TIP OUR HAT TO PAT TOPOLINSKI FOR PITCHING IN. THE EXTRA SET OF HANDS WAS AWESOME, THANK YOU.
(PAT)>> THANKS VERY MUCH.
(MIKE)>> WE ALSO CREDIT THIS BUILD TO KEITH DORTON, WHO SHARED HIS SKILLS AND KNOWLEDGE WITH ALL OF US. AND FOR PASSING IT DOWN TO HIS SON JEFF TO KEEP THE LEGACY ALIVE FOR THE NEXT GENERATION. HERE'S SOMETHING FOR YOU HARLEY GUYS THAT HAVE A 2002 THROUGH 2008 TOURING EDITION. IT'S ACCEL'S STEALTH SUPER COILS FOR VTWIN ENGINES. NOW THESE THINGS ELIMINATE IGNITION WIRES BY MOUNTING THE COIL DIRECTLY TO THE SPARK PLUG. NOW THE CAST ALUMINUM HOUSING ACTUALLY ACTS AS A HEAT SINK TO PULL HEAT AWAY FROM THE CYLINDER HEAD. NOW ALL THE WIRING IS HIDDEN FOR A CLEAN CUSTOM LOOK, AND THE COILS COME WITH A LIMITED LIFETIME WARRANTY.
NOW YOU CAN FIND YOURS AT SUMMIT RACING DOT COM'S POWER SPORTS SUPER STORE FOR JUST UNDER $230 BUCKS. SAFETY IS ALWAYS OUR TOP PRIORITY, AND THIS SPARCOJ TOP DRIVING SUIT IS AN EASY WAY TO MAKE IT YOURS. NOW THIS IS A ONE PIECE THREE LAYER DESIGN MADE OF FLAME RETARDANT COTTON. IT SURPASSES SFI'S THREE POINT TWO AFIVE STANDARDS AND IS AVAILABLE IN TWO TONE COLOR COMBINATIONS. NOW YOU CAN PICK THEM UP IN SEVERAL SIZES, COLORS, AND THEY'RE AVAILABLE AT SUMMIT RACING FOR RIGHT AT $300 BUCKS. NOW IF YOU PLAN ON GOING FAST, YOU'VE GOT TO STAY SAFE. WE'LL SEE YOU NEXT TIME.

A SHORT SOAK FREED UP SOME PISTONS BUT THE REST PUT UP A BATTLE. THE BLOCK HAD BEEN PREVIOUSLY BORED AND APPEARED SOLID, BUT ONLY A TRIP TO A MACHINE SHOP CAN CONFIRM IT. AFTER A SHOT PEEN AND SOME MAGNAFLUXING WE FOUND
SEVERAL SMALL CRACKS BETWEEN SOME WATER JACKETS AND THE BOLT HOLES. FORTUNATELY AN EASY FIX, BY DRILLING OUT THE ORIGINAL HOLES AND DRIVING IN A LUBED INSERT WITH A BOLT. ONCE SEATED AND THE BOLT REMOVED, THE NEW THREAD STOPS THE CRACK, GIVING THE NEW STUDS A STRONGER CLAMPING AREA. THE CYLINDERS CLEANED UP WELL, NO SLEEVES NEEDED. SO WE HAVE THE GREEN LIGHT TO CONTINUE. THE VALVE SEATS WERE NEXT AND THE OLD ONES PUT UP A FIGHT AS WELL. WITH A PILOT IN PLACE THE NEW ONES ARE DRIVEN IN. WE GAVE THE EXHAUST A STANDARD THREE ANGLE VALVE JOB, BUT THE INTAKES GOT OPENED UP A LITTLE, DESHROUDED, THEN A THREE ANGLE CUT AS WELL. AND THAT'S AS FAR AS TIME ALLOWED US TO GO. ANOTHER PROJECT CALLED US AWAY. SO WE CALLED ON AN OLD FRIEND TO TAKE OVER. HE GREW UP IN THE HEART OF NASCAR COUNTRY WITH AN EARLY PASSION FOR SPEED.
WHILE HE ENJOYED THE THRILL OF DRIVING RACE CARS, KEITH DORTON LOVED THE CHALLENGE OF MAKING POWER FOR THEM. IT CONSUMED HIS IMAGINATION AND CREATIVITY. HIS ENGINES HAVE BEEN WINNING RACES FOR FIVE DECADES. NOW IN THE 1960'S HIS CYLINDER HEAD MAKING MAGIC PROVIDED THE WINNING EDGE FOR LEGENDS LIKE JUNIOR JOHNSON, BOBBY ALLISON, AND CALE YARBOROUGH.

(KEITH)>> YOU'RE GONNA SPEND A LOT OF MONEY AND GOT A TOTALLY UNIQUE CHASSIS AND BODY COMBINATION, WHY NOT PUT A UNIQUE ENGINE COMBINATION. IT'S PRETTY EASY TO MAKE HORSEPOWER, BUT WHAT WE HAVE TO DO FOR THIS APPLICATION IS MAKE DRIVABLE POWER.
(MIKE)>> AND THAT'S WHY WE CALLED KEITH. YOU'LL SEE HOW HE DOES IT AFTER THE BREAK.
(ANNOUNCER)>> UP NEXT, KEITH IS HERE, LET THE BUILD BEGIN!
(MIKE)>> WE'RE BACK AND SO IS THE FLATHEAD, ALONG WITH LEGENDARY ENGINE BUILDER KEITH DORTON. HE ALSO BROUGHT HIS PASSION.
(KEITH)>> YOU KNOW THE COOLEST SOUNDING ENGINES YOU'VE EVER HEARD HAVE A UNIQUE SOUND,
AND THEY RUN SO SMOOTH. AND YOU KNOW, IN A STOCK FORM THEY WERE JUST AS QUIET AS A CADILLAC ENGINE. IT WAS GOOD TO FIND A BLOCK THAT WAS IN AS GOOD A CONDITION AS THIS ONE IS, EVEN THOUGH IT HAD SOME CRACKS IN IT THAT ARE COMMON WITH THE FLATHEADS. BUT THIS ONE'S ABOUT AS GOOD AS YOU'RE GONNA FIND NOW. ALL THAT WE HAD TO DO AT THE SHOP, AND IT WASN'T A MUST, WAS WE DID THE RELIEVING THE BLOCK. WHICH THE AREA BETWEEN THE VALVES AND THE CYLINDER, WE DROPPED IT ABOUT 80 TO 90 THOUSANDTHS TO INCREASE THE
AIR FLOW FROM THE VALVES TO THIS CYLINDER, WHICH IS PART OF THE COMBUSTION CHAMBER. I REALLY WANT TO START COLLECTING SOME PARTS MYSELF
AND YOU KNOW, WANT TO BUILD ANOTHER HOT ROD ONE DAY. AND IT'LL HAVE A FLATHEAD IN IT WHEN I DO.
(MIKE)>> THE GOAL FOR THIS ENGINE IS PRETTY SIMPLE. WE WANT A SMOOTH RUNNING USER FRIENDLY ENGINE THAT DOESN'T REQUIRE A LOT OF MAINTENANCE. NOW FOR THAT WE'RE USING PARTS FROM SEVERAL
MANUFACTURERS THAT HAVE BEEN IN THE PERFORMANCE WORLD FOR YEARS. LIKE SCAT WITH THEIR POPULAR FORD FLATHEAD ROTATING ASSEMBLY. NOW THIS IS THEIR CAST CRANK WITH A FOUR-250 STROKE THAT HAS BEEN INTERNALLY BALANCED WITH THE REST OF THE KIT. NOW ATTACHED TO IT ARE SET OF HBEAM SEVEN INCH RODS THAT ARE HELD TOGETHER WITH ARP 8740 ROD BOLTS. NOW THE PISTONS HAVE A COOL LITTLE STORY IN THEMSELVES. LIKE THE ORIGINALS WE BUSTED OUT OF THE BLOCK, THESE HAVE A SLIGHT DOME. NOW IN THE FLATHEAD WORLD THEY'RE CONSIDERED A FLAT TOP. NOW AS FAR AS A HORSEPOWER GOAL, WE'RE GONNA LET THE DYNO DECIDE CAUSE WE JUST DON'T KNOW. THE FIRST PART OF THE BUILD WILL BE THE BOTTOM END. NOW A SET OF CLEVITE BEARINGS WILL FILL THE FLATHEAD'S THREE MAIN JOURNALS. ROYAL PURPLE ASSEMBLY LUBE WILL PROTECT THE BEARINGS AS WE ASSEMBLE IT. NOW THE CRANK SHAFT IS SCAT'S 9,000 SERIES MADE FOR THE STREET AND STRIP. IT WILL GIVE OUR FLATHEAD 304 CUBIC INCHES. NEXT UP ARE THE ORIGINAL MAIN CAPS.
NOW THEY'RE FILLED WITH THE OTHER HALVES OF THE CLEVITE BEARINGS.
ARP BOLTS WILL ANCHOR THEM IN.
WITH ARP'S ULTRA TORQUE ON THE BOLTS WE CAN TORQUE THE FIRST TWO CAPS TO 40 FOOT POUNDS. FORCING THE CRANK TOWARDS THE FRONT OF THE ENGINE WILL ALIGN THE TWO HALVES OF THE THRUST BEARING, WHICH IS AT THE REAR. NOW TORQUE THAT CAP TO 40 FOOT POUNDS. SET UP THE MAGNETIC BASE AND DIAL GAUGE ON THE CRANK
SNOUT AND WITH THE READING AT ZERO WE'LL ROCK THE CRANK FROM FRONT TO BACK TO CHECK THE THRUST CLEARANCE. RIGHT AT SIX, WHICH IS IN SPEC. NOW TORQUE ALL THE CAPS TO THE FINAL VALUE OF 70 FOOT POUNDS.
BEFORE WE MOVE ON A MASKING JOB AND SOME OLD TINS FROM THE ORIGINAL ENGINE WILL GIVE US THE COVER WE NEED TO ADD SOME COLOR.
HERE'S A PRELUDE OF THINGS TO COME. IT SPEAKS FOR ITSELF BUT WE'LL TELL YOU MORE ABOUT IT ON THE DYNO. DUPLICOLOR'S GRAY ENGINE PRIMER AND RED ENGINE
PAINT WILL GIVE THE FLATTY A SLICK LOOK. MOVING FORWARD WITH THIS BUILD REQUIRES THE NUMBER ONE PISTON TO BE IN PLACE. THE SCAT ROD IS HELD TO THE ROSS FORGED PISTON WITH A FLOATING PIN. THE SPIRAL LOCKS WILL KEEP IT IN PLACE.
GAPPING THE RINGS IS A MUST. KEITH IS USING OUR GOODSON FILER TO OPEN THE GAPS, WHICH WILL AVOID THEM FROM TOUCHING WHEN THE ENGINE GETS UP TO TEMPERATURE, WHICH WOULD LEAD TO A MAJOR FAILURE. THE RING PACK IS FROM TOTAL SEAL, THE BALANCING ACT IS FROM EXPERIENCE.
(KEITH)>> YOU KNOW I WAS THE ONLY REAL GEARHEAD IN MY CLASS WHEN I WENT TO SCHOOL. OF COURSE THAT MEANT I ALWAYS HAD TO FIX THE TEACHERS CARS, BUT MAYBE THAT'S THE ONLY WAY I PASSED TOO.
(MIKE)>> WITH ASSEMBLY LUBE IN PLACE AND THE PISTON OILED, WE CAN FILL THE THREE POINT THREESEVENFIVE INCH BORE. NOW THE ROD BEARING IS FROM A 327 SMALL BLOCK CHEVY THAT HAD BEEN NARROWED AND CHAMFERED TO THE FLATHEAD'S ROD JOURNAL WIDTH. NEXT UP IS THE ISKY FLAT TAPPET CAM SHAFT THAT STILL HOLDS THE NAME THREE QUARTER RACE CAM. NOW IT'S DESIGNED FOR MILD STREET AND GOOD LOW SPEED POWER. LIFT IS A SINGLE PATTERN AT 364 ON THE
INTAKE AND EXHAUST. THESE ISKY LIFTERS HAVE DEEP GROOVES IN THEIR BODY TO HOLD OIL AND LUBRICATE THE LIFTER BORE AS
THEY MOVE UP AND DOWN. THE SMALL NUT IS THE ADJUSTER TO SET THE VALVE LASH. BACK IN THE DAY ADJUSTABLE LIFTERS WERE NOT AVAILABLE. SO TO GET THE VALVE'S LASH, GRINDING ON THE VALVE'S STEM
OR ALTERING THE VALVE'S SEAT WAS THE ANSWER. NOW THE VALVE ASSEMBLIES CAN BE PUT TOGETHER. FIRST APPLY ASSEMBLY LUBE ON THE VALVE STEM. THEN THE VALVE GUIDE CAN GO ON FOLLOWED BY A SHIM, THE VALVE SPRING, RETAINER, AND FINALLY THE LOCKS. NOW IT GOES INTO THE BLOCK AS AN ASSEMBLY. THE INTAKE GOES TOGETHER THE SAME WAY BUT USES A SEAL ON THE GUIDE. THE NEXT STEP CAN BE TRICKY BUT WE HAVE THE RIGHT TOOL, SO IT SHOULD BE A BREEZE. BY USING A VALVE GUIDE TOOL SPECIFIC TO THE FLATHEAD, WE CAN PULL THE GUIDES DOWN AND INSTALL THE RETAINERS WITH A PAIR OF NEEDLE NOSE PLIERS. WITH THE EXHAUST VALVE JUST STARTING TO OPEN, USING A
FEELER GAUGE CHECK THE LASH BETWEEN THE LIFTER AND THE VALVE TIP. WE HAVE 12 THOUSANDTHS, WHICH IS A LITTLE TIGHT. NOW TO MAKE AND ADJUSTMENT THE LIFTER NEEDS TO BE MOVED UP AND A SMALL ALLEN SOCKET PLACED THROUGH THIS HOLE, WHICH KEEPS THE LIFTER FROM ROTATING.
USING A SEVENSIXTEENTHS WRENCH, THE ADJUSTOR IS TURNED IN TO OPEN THE LASH. NOW ROTATE THE ENGINE AGAIN SO THE EXHAUST VALVE STARTS
TO OPEN, AND CHECK THE LASH, WHICH IS RIGHT ON THE MONEY AT 14 THOUSANDTHS. SO FAR THIS BUILD IS MOVING VERY SMOOTH. MORE TO COME AFTER THE BREAK.
(ANNOUNCER)>> SO WHO'S THE COOLEST, THE FLATHEAD OR KEITH? MORE TO COME!
(MIKE)>> AT THIS POINT THE VALVES ARE IN AND LASHED ON THIS 1950'S FORD FLATHEAD. SO WE'LL LOCK THE CAM IN PLACE WITH THE ORIGINAL TIMING COVER, DRESSED WITH A NEW CRANK SEAL, SILICONE ON THE MATING SURFACE, AND A SMALL AMOUNT OF EXTREME PRESSURE LUBE WHERE THE NOSE OF THE CAM CONTACTS THE THRUST SURFACE OF THE COVER. WITH THE REMAINING PISTONS IN PLACE AND THE CAPS TORQUED TO 50 FOOT POUNDS, ALL THE INTERNAL ARE DONE. AND TO CONFIRM CAM SPECS, KEITH ALWAYS TAKES TIME FOR THE DEGREE WHEEL. NOW WE CAN INSTALL THE ARP HEAD STUDS INTO THE BLOCK. THEY WILL GIVE US THE EXTRA CLAMPING FORCE NEEDED TO
SEAL THE FLATTY'S HEADS. TO CONTROL ALL THE CRANK SHAFT VIBRATION, NOT JUST THAT IN A LIMITED FREQUENCY RANGE, WE'RE USING A FLUID DAMPER BALANCER ON THIS FLATHEAD. NOW THIS THING IS CONSTRUCTED OF ONLY THREE PIECES, THE HUB, A LASER WELDED OUTER SHELF, AND INSIDE IS A HIGHLY VISCOUS SILICONE FLUID THAT ACTUALLY ABSORBS ALL THAT VIBRATION. PLUS IT'S SFI APPROVED AND WE'RE READY TO PUT IT ON. IT REDUCES WEAR ON THE MAIN BEARINGS AND TIMING GEAR, HAS A SIX INCH DIAMETER AND IS MADE TO RUN VBELTS. NOW IT'LL REST AGAINST A SPACER THAT RETAINS THE OIL SLINGER. SUMMIT RACING SUPPLIED THE MELING STANDARD VOLUME OIL PUMP FOR THIS BUILD. IT DOES NOT USE A GASKET AND IS HELP IN PLACE WITH ONE FIVESIXTEENTHS BOLT. THE NEXT TWO PARTS WERE HARD TO FIND UNTIL WE FOUND THIS GUY, HAL FROM HAL'S GARAGE IN FAYETTE, OHIO.
NOW HE'S A WELL KNOWN GO TO SOURCE FOR OLD FLATHEAD PARTS. IF YOU WANT TO TAKE A TRIP BACK IN AUTOMOTIVE TIME, GIVE HIS LITTLE GARAGE A VISIT. THE OIL PUMP PICK UP IS AN ORIGINAL
PULLED BY HAL HIMSELF. IT CAME TO US WITH A MATCHING PAN THAT WAS IN AWESOME SHAPE FOR BEING OVER 61 YEARS OLD.
WITH THE SEALS INSTALLED WE CAN DROP THE PAN ON FEL PRO GASKETS AND WE'RE DONE WITH THE BOTTOM END. COPPER FEL PRO HEAD GASKETS ARE NEXT. NOW IT'S RECOMMENDED TO USE A SEALER LIKE VHT'S COPPER GASKETS SEALANT ON BOTH SIDES TO IMPROVE THEIR SEALING CHARACTERISTICS. GENTLY WORK THE GASKET OVER THE STUDS KEEPING IT EVEN AS IT GOES DOWN. VIC EDELBROCK SENIOR DESIGNED THE FIRST ALUMINUM PERFORMANCE FLATHEAD CYLINDER HEAD BACK IN 1938. NOW FROM THAT POINT ON PRODUCTION NEVER ENDED.
NOW THIS IS THE '49 THROUGH '53 VERSION, AND IT GOT ITS
NAME FROM THE THIN DESIGN. NOW UNDERNEATH THE COMBUSTION CHAMBER LOOKS SMALL BUT IT'S ACTUALLY 65cc. THEY'RE RIBBED INTERNALLY AND EXTERNALLY FOR STRENGTH, AND HAVE LARGE WATER JACKETS FOR BETTER COOLING. TO PROTECT THE SHINY FINISH OF THE NUT I'M LAYING A PIECE OF TISSUE OVER THEM, THEN PLACING THE SOCKET OVER IT. THIS WILL HELP AVOID SCARING TO THE HEX
PORTION OF THE NUT.
BOTH HEADS WILL BE TORQUED IN SEQUENCE TO 60 FOOT POUNDS. AND FOR THE FINAL TIME HERE'S EDELBROCK'S VINTAGE TRIPOWER INTAKE SETUP, AND IT'S NOT JUST FOR SHOW.
(KEITH)>> I THINK IT'S GREAT THAT YOU CAN BOLT THESE CARBS ON RIGHT OUT OF THE BOX.
GET YOUR RESULTS, WHICH I'M SURE WE'RE GONNA GET HERE.
THE MANIFOLD LOOKS SO COOL TOO.
(MIKE)>> FOR SPARK A MALLORY UNILITE ELECTRONIC DISTRIBUTOR, A HUGE LEAP IN TECHNOLOGY FROM THE '50'S. NEW HIGH FLOW WATER PUMPS ARE NEXT, AND THESE WILL BE THE LAST PARTS KEITH INSTALLS FOR US.
(KEITH)>> WE'VE GOT TO PUT SOME FUEL LINES ON IT, OR
YOU DO, CAUSE I'VE GOT TO GET BACK AND GET TO WORK. WE'VE BEEN GONE LONG ENOUGH.
(MIKE)>> KEITH DID WHAT HE CAME TO DO, REVIVING AN IMPORTANT PIECE OF HISTORY.
(KEITH)>> REALLY A FUN PROJECT TO COME BACK AND
WORK ON SOMETHING THIS OLD. AND I'M VERY CONFIDENT THAT WE'RE GONNA GET SOME GOOD RESULTS OUT OF IT.
(MIKE)>> AND IF KEITH SAYS SO, SO IT SHALL BE.
(ANNOUNCER)>> YOU HEARD THE MAN, UP NEXT, DYNO TIME!
(MIKE)>> WE'RE BACK AND READY FOR THE DYNO, BUT AS IT TURNS OUT I'M NOT ALONE AFTER ALL. ANOTHER HIGH PROFILE ENGINE BUILDER, PAT TOPOLINKSKI, CAME BY TO WATCH THE RUN, BUT I'M PUTTING
HIM TO WORK INSTEAD.
(PAT)>> THEY'RE EASY TO MODIFY, EASY TO WORK ON. I LOVE THEM TO TELL YOU THE TRUTH.
(MIKE)>> YOU MAY RECOGNIZE HIS FACE, HE HELPED US WITH OUR DRIVEWAY RESCUE SEGMENTS IN THE PAST. BUT HIS CLAIM TO FAME IS BEING A TEAM MEMBER OF KB RACING'S MULTICHAMPIONSHIP WINNING NHRA PRO STOCK TEAM, WHERE HIS DUTIES INCLUDED CLUTCH AND TRANSMISSION SETUP, ENGINE DEVELOPMENT, AND ANY THING ELSE HE COULD GET HIS HANDS ON.
AND TODAY IT'S A FLATHEAD.
(PAT)>> YOU KNOW I CAME HERE TO WATCH, BUT I'M A HORRIBLE SPECTATOR. AND IF YOU DIDN'T COME HERE TO PITCH IN, YOU
SHOULDN'T BE HERE ANYWAY.
(MIKE)>> PATRIOT TIGHT TUCK STREET ROD HEADERS WILL DIRECT THE EXHAUST GASES OUT OF THE ENGINE. NOW TO SET THE BELT TENSION WE'RE USING EDELBROCK'S OFFSET ALTERNATOR BRACKET AND TOPPING IT OFF WITH POWERMASTER'S POWER GEN 90 AMP 12 VOLT ALTERNATOR. EDELBROCK'S TRIPLE DEUCE FUEL LINE KIT WILL MAKE THE PLUMBING SUPER EASY. NOW THE 94 TWO BARREL CARBS WERE BORN IN 1938 AND
PRODUCTION STOPPED IN '57. IN 2010 EDELBROCK MADE THEM AVAILABLE ONCE AGAIN TO FEED NOSTALGIA ENGINES LIKE THIS. REMEMBER THAT OIL PUMP PICK UP WE INSTALLED EARLIER? WELL THIS SCREEN IS THE ONLY FILTRATION A FLATHEAD EVER GOT, WHICH ISN'T GOOD ENOUGH. SO KEITH MADE SOME MODIFICATIONS TO THE BACK SIDE OF THE BLOCK. NOW THAT'S GONNA LET US RUN A REMOTE OIL FILTER. NOW THE BLUE FITTING IS PRESSURE INTO IT AND THE BLACK FITTING IS PRESSURE BACK INTO THE ENGINE. FROM THE MILODON REMOTE FILTER ADAPTER WE RAN THE TWO LINES TO THE FITTINGS AT THE BACK OF THE ENGINE, AND ONE MORE LINE TO MONITOR PRESSURE AT THE DYNO CONSOLE. NOW THE ALL IMPORTANT FILTER. WE'LL PRIME IT WITH FIVE AND A HALF QUARTS OF ROYAL PURPLE BREAK IN OIL. A QUICK CHECK FOR LEAKS, PRESSURIZE THE FUEL SYSTEM
TO FILL UP THE BOWLS. KEITH, HEY, HOW ARE YOU. I MADE A COURTESY CALL TO LET KEITH KNOW
WHAT WAS GOING ON. I'LL CALL YOU THIS AFTERNOON.
(PAT)>> WHOA!
(MIKE)>> WOW!
(PAT)>> ALRIGHT!
(MIKE)>> THAT TIMING WAS DEAD ON. OUR DISTRIBUTOR HAS 14 DEGREES OF MECHANICAL ADVANCE BUILT IN. TO START WE'LL RUN 24 DEGREES OF TOTAL TIMING AND ADVANCE IT FROM THERE. NOW WE CAN BREAK IN THE CAM SHAFT BY RUNNING THE ENGINE FROM 15 TO 2,200 RPM FOR 20 MINUTES. WITH GREAT OIL PRESSURE, THE RECOMMENDED FUEL PRESSURE, WE'RE READY TO ADJUST THE CARBURETORS. WE'RE GONNA SET THE THROTTLE BLADES ON EACH CARBURETOR SO THEY OPEN EVENLY. THEN WE NEED TO SET IT UP SO THEY'RE SYNC'ED TOGETHER BASED OFF OF VACUUM. NOW FOR THAT WE'LL GET HELP FROM THE UNISON TOOL FROM EDELBROCK. NOW IT'S TIME TO FIRE IT UP.
WE'LL GET THE ENGINE TO IDLE BY OPENING THE THROTTLE BLADES OF EACH CARB EVENLY. NOW PLACE THE UNISON ON THE CENTER CARB AND TURN THE AIR FLOW CONTROL TO GET THE RED INDICATOR IN THE CENTER OF THE TUBE. WITHOUT CHANGING THE AIR CONTROL VALVE, PLACE IT ON THE OTHER CARBS AND ADJUST THE IDLE CONTROL SCREW TO MAKE THE RED INDICATOR REACH THE SAME LOCATION
AS THE CENTER CARB. NOW WE CAN REATTACH THE LINKAGE AND CHASE DOWN SOME OLD SCHOOL GRUNT. GOT YOUR SEATBELT ON AND YOUR HELMET STRAPPED?
(PAT)>> I'M READY! LET HER RIP TATER CHIP! [engine revving]
(MIKE)>> 156, 247.
(PAT)>> AWESOME, I LIKE IT. LETS THROW SOME TIMING AT IT AND SEE HOW IT LIKES IT.
LETS SNEAK IT UP TO ABOUT 26. [ engine revving ]
(MIKE)>> 159, 264.
(PAT)>> NICE!
(MIKE)>> THAT'S NICE, NICE SMOOTH GRAPH TOO,
AND IT'S STILL CLIMBING. TO FIND ITS THRESHOLD WE TRIED 28 DEGREES AND
LOST A LITTLE OF BOTH. 157, 253, BUT STILL COOL FOR BEING OVER 60 YEARS OLD.
(PAT)>> SEE THE COOLNESS FACTOR ON THIS ONE IS OFF THE CHARTS.
(MIKE)>> SO IT'S BACK TO 26 DEGREES FOR ONE LAST PULL. WE'LL CLAIM VICTORY AT 159 HORSEPOWER AND 257 FOOT POUNDS OF TORQUE. YOU GLAD YOU CAME BY?
(PAT)>> I'M GLAD I CAME BY, I'M GLAD I GOT TO BE ABLE TO HELP WITH IT. THIS IS ULTRA COOL. IT'S A GREAT LITTLE ENGINE, IT LOOKS GREAT.
(MIKE)>> WE TIP OUR HAT TO PAT TOPOLINSKI FOR PITCHING IN. THE EXTRA SET OF HANDS WAS AWESOME, THANK YOU.
(PAT)>> THANKS VERY MUCH.
(MIKE)>> WE ALSO CREDIT THIS BUILD TO KEITH DORTON, WHO SHARED HIS SKILLS AND KNOWLEDGE WITH ALL OF US. AND FOR PASSING IT DOWN TO HIS SON JEFF TO KEEP THE LEGACY ALIVE FOR THE NEXT GENERATION. HERE'S SOMETHING FOR YOU HARLEY GUYS THAT HAVE A 2002 THROUGH 2008 TOURING EDITION. IT'S ACCEL'S STEALTH SUPER COILS FOR VTWIN ENGINES. NOW THESE THINGS ELIMINATE IGNITION WIRES BY MOUNTING THE COIL DIRECTLY TO THE SPARK PLUG. NOW THE CAST ALUMINUM HOUSING ACTUALLY ACTS AS A HEAT SINK TO PULL HEAT AWAY FROM THE CYLINDER HEAD. NOW ALL THE WIRING IS HIDDEN FOR A CLEAN CUSTOM LOOK, AND THE COILS COME WITH A LIMITED LIFETIME WARRANTY.
NOW YOU CAN FIND YOURS AT SUMMIT RACING DOT COM'S POWER SPORTS SUPER STORE FOR JUST UNDER $230 BUCKS. SAFETY IS ALWAYS OUR TOP PRIORITY, AND THIS SPARCOJ TOP DRIVING SUIT IS AN EASY WAY TO MAKE IT YOURS. NOW THIS IS A ONE PIECE THREE LAYER DESIGN MADE OF FLAME RETARDANT COTTON. IT SURPASSES SFI'S THREE POINT TWO AFIVE STANDARDS AND IS AVAILABLE IN TWO TONE COLOR COMBINATIONS. NOW YOU CAN PICK THEM UP IN SEVERAL SIZES, COLORS, AND THEY'RE AVAILABLE AT SUMMIT RACING FOR RIGHT AT $300 BUCKS. NOW IF YOU PLAN ON GOING FAST, YOU'VE GOT TO STAY SAFE. WE'LL SEE YOU NEXT TIME.
