Building a 572 c.i. Hemi In Hopes Of Making 900 Horsepower

(JOE)>> IT'S MOPAR MADNESS TODAY ON HORSEPOWER TV. STAY TUNED, YOU'LL SEE WHY.

(JOE OFF CAMERA)>> TODAY ON HORSEPOWER TV, FOR YEARS HEMI'S RULED THE ROADS AND STRIPS. WE'LL BUILD ONE OF THESE HIGHPOWERED HEMI'S, A 572 CUBIC INCH MONSTER THAT'LL MAKE OVER 900 HP. PLUS WE'LL TAKE YOU TO THE TRACK WHERE EVERYTHING THAT'S OLD IS NEW AGAIN, IN THE FAST, FUN, AND MEMORABLE WORLD OF NOSTALGIA STREET RACING. SO HANG ON FOR HORSEPOWER TV! [ MUSIC ]

(JOE)>> HI AND WELCOME TO THE SHOP. IF YOU WERE FISHING FOR HORSEPOWER BACK IN THE MUSCLE CAR ERA, CHANCES ARE YOU WERE HOPING TO HOOK ONE OF THESE CUDAS. THIS IS A 1970 WITH ALL THE RIGHT BAIT ON THE OUTSIDE - THE HOCKEY STICK STRIPE, FATFORTHETIME F-60 GOODYEAR RUBBER, AND THOSE UNMISTAKABLE GILLS ON THE ROCKER PANEL. BUT, THE REAL CATCH WAS UNDER THE HOOD AND UNDER THIS MASSIVE SHAKER SCOOP. I'M TALKING ABOUT THE 426 HEMI. THIS ONE, BY THE WAY, WAS "CAUGHT" BY DEWEY GREEN IN ALABASTER, ALABAMA.

(CHUCK)>> THE HEMI MADE ITS MARKS FROM THE CRUISING CIRCUITS AROUND THE COUNTRY TO THE HIGHBANKS OF NASCAR. BUT, WHERE IT REALLY LEFT AN IMPRESSION WAS ON THE QUARTERMILE WHERE DRAG RACERS LIKE DICK LANDY AND SOX AND MARTIN LED A WHOLE HERD OF ELEPHANTS DOWN THAT DRAG STRIP AND INTO THE SUPER STOCK RECORD BOOKS. NOW, TODAY, YOU'RE GONNA FIND THE HEMI POWERING EVERYTHING FROM TOP FUEL DRAGSTERS AND FUNNY CARS TO SUPER COMP DRAGSTERS LIKE THIS ONE BELONGING TO JEFF AND FRED HURST.

(JOE)>> NOW, TODAY ON THE SHOW, WE'RE GONNA BUILD ONE OF THESE LEGENDARY HEMI'S. AND, IF YOU THINK BIGGER IS BETTER, YOU'RE GONNA LOVE THIS. IT'S 572 CUBIC INCHES AND SHOULD CRANK OUT OVER 900 HORSEPOWER.

(CHUCK)>> NOW, THAT'S IMPRESSIVE. I TELL YA' WHAT, THE BASIS FOR THIS BUILDUP IS AN INDYMAXX ALL ALUMINUM CYLINDER BLOCK. NOW, STOP AND THINK ABOUT IT FOR JUST A LITTLE BIT. THAT'S OVER 900 HORSEPOWER FROM AN ENGINE THAT DOESN'T WEIGH A WHOLE LOT MORE THAN A SMALL BLOCK CHEVY.

(JOE)>> THE BOTTOM END BEGINS WITH THIS INDY CALLIE'S CRANK. IT'S A FORTYTHREE FORTY PIECE THAT'S BEEN TRIPLE HEAT TREATED AND STRESS RELIEVED. NOW, THE STROKE ON THIS THING IS FOUR AND ONEHALF INCHES.

(CHUCK)>> THAT BIG CRANK IS GONNA HANG A SET OF THESE BILL MILLER ALLALUMINUM RODS AND A SET OF THESE FOUR AND ONEHALF INCH BORE WEISCO PISTONS THAT HAVE BEEN FITTED WITH SPEEDPRO RINGS.

(JOE)>> NOW, BEFORE WE BOLT UP THIS BOTTOM END, THIS HEMI'S A UNIQUE ANIMAL. THE FIRST THING WE HAVE TO DO IS CHECK OUR VALVE TO VALVE CLEARANCE.

(CHUCK)>> WELL I'VE GOT THE CAM SHAFT.

WITH THE CYLINDER HEAD BOLTED ON AND THE VALVES IN THE OVERLAP POSITION, INSERT THE FEELER GAUGE FROM THE BOTTOM OF THE BORE AND CHECK FOR A MINIMUM OF .030 BETWEEN THE VALVES. HERE'S A NEAT FEATURE ABOUT THE INDY LEGEND HEMI HEAD. THE EXHAUST VALVE HAS BEEN ROTATED TWO DEGREES AWAY FROM THE INTAKE. NOW THAT LETS US USE A LARGER INTAKE VALVE AND INCREASES THE CLEARANCE BETWEEN 'EM.

(JOE)>> NOW, THAT WE'VE CHECKED OUR VALVE CLEARANCE, WE CAN START BUILDING THIS BOTTOM END STARTING WITH OUR MAIN BEARINGS. NOW THESE FEDERAL MOGULS ARE NARROWER THAN STOCK WITH A CHAMFERED EDGE TO MATCH THE SPECIAL RADIUS ON OUR CRANK FILLET. AFTER WE POP 'EM IN, WE'LL MAKE SURE WE USE LOTS OF THIS ASSEMBLY LUBE.

(CHUCK)>> BELIEVE IT OR NOT, THIS BLOCK ONLY WEIGHS 133 POUNDS, AND 30 POUNDS OF THAT ARE THESE STEEL BILLET MAIN CAPS. NOW, THIS BOTTOM END IS TRULY BULLET PROOF. ALL FIVE CAPS ARE CROSSBOLTED.

MAKE SURE YOU TORQUE THE CENTER BOLTS FIRST TO 80 FOOT POUNDS.

AND, FINISH UP WITH THE SIDE BOLTS AT 70 FOOT POUNDS.

(JOE)>> THESE BME RODS ARE MADE FROM A CUSTOM AEROSPACE ALLOY. THE ALUMINUM HAS BEEN FORGED UNDER EXTREME PRESSURE FOR SUPERIOR GRAIN FLOW. AND, THEY'VE BEEN POLISHED TO REDUCE THE CHANCES OF STRESS RISERS. NOW, THEY USED TO CALL OLD HEMI PISTONS BRICK HOUSES BECAUSE THE UNDERNEATH WAS PRETTY SOLID. THESE WEISCOS ARE MADE FROM A DEDICATED HEMI DIE THAT ELIMINATES MOST OF THAT EXTRA WEIGHT AND THE NEED FOR ANY INTERNAL MILLING.

(CHUCK)>> WITH THE NUMBER ONE PISTON INSTALLED, NOW WE CAN SET UP OUR MILODON GEAR DRIVE. NOW, UNLIKE OTHER CAM DRIVES WHERE YOU SIMPLY HAVE TO LINE UP TWO DOTS TO INSTALL THE CAM STRAIGHT UP, HERE WE FIRST HAVE TO ESTABLISH THAT DOT LOCATION. TO DO THIS, DROP IN THE LIFTERS THAT'LL BE USED IN THE ENGINE. THEN THE DIAL INDICATOR TO MEASURE CAM LIFT. INSTALL THE DEGREE WHEEL AND THE POINTER. AND AFTER BRINGING THE NUMBER ONE PISTON TO TOP DEAD CENTER, LINE UP THE POINTER ON THE WHEEL. THE CAM CARD TELLS US THE INTAKE OPENS AT 32 DEGREES AT .050 CAM LIFT. BY TURNING THE CRANK TO 32 DEGREES, AND ROTATING THE CAM TO .050 LIFT, YOU CAN SLIDE THE CAM GEAR ON, MAKE YOUR MARKS, AND THAT'LL ALLOW US TO INSTALL THE CAM STRAIGHT UP. THEN, WE CAN INSTALL THE OTHER SEVEN PISTONS AND THE CAM COVER. USING A FEELER GAUGE TO MAINTAIN CAP ALIGNMENT, TORQUE THE ROD BOLTS TO 75 FOOT POUNDS AND MAKE SURE YOU USE PLENTY OF OIL SO YOU GET AN ACCURATE TORQUE READING.

(JOE)>> WE'RE GONNA BUTTON UP OUR BOTTOM END WITH THIS WET SUMP OIL PAN FROM CHARLIE'S. NOW, THIS THING'S GOT A UNIQUE FEATURE INSIDE HERE, A PICKUP THAT ACTUALLY SWINGS. THIS IS HOW IT WORKS, 'COURSE THE SCREENS ON THE BOTTOM HERE. WHEN YOU ACCELERATE IT SWINGS BACK, WHEN YOU DECELERATE IT SWINGS FORWARD. 'COURSE THAT WAY, IT STAYS SUBMERGED IN OIL ALL THE TIME. NOW INDY HAS ELIMINATED MOST OF THE STANDARD PAN FLANGE THAT USED TO BE HERE. BY OPENING IT UP, THERE'S LESS OIL BOUNCING AROUND IN THE PAN AND WRAPPING ITSELF AROUND THE CRANK. NOW THAT'S GOOD FOR 15 TO 20 HORSEPOWER. THIS PAN DOESN'T USE A GASKET. INSTEAD WE'RE GONNA USE SOME RTV. LET ME SHOW YOU A TIP. FOR A NEATER JOB, WE JUST TRACE AROUND THE PAN WITH A MARKER. THEN, APPLY THE RTV INSIDE THE MARK. WELL, THAT'S IT FOR THE BOTTOM END OF OUR HEMI. WE'LL CALCULATE THE COMPRESSION RATIO AND FINISH THE TOP END AFTER THIS. [ MUSIC ] (JOE OFF CAMERA)>> LATER IN THE SHOW A QUICK TRIP DOWN MEMORY LANE. IT'S THE WORLD OF NOSTALGIA RACING WHERE DRIVERS OF TODAY ENJOY A BLAST FROM THE PAST. ( )>> WHEN THEY BUILT THIS CAR, IT WAS BUILT WITH ONE PURPOSE IN MIND. THAT'S TO GO FAST AND GO STRAIGHT. (JOE OFF CAMERA)>> WE'LL COME STRAIGHT BACK AFTER THIS.

[ MUSIC ]

(JOE)>> WELCOME BACK TO OUR LEGEND HEMI BUILDUP. WELL MY PARTNER'S JUST FINISHED BOLTING ON THAT EXTERNAL BILLET OIL PUMP. I GUESS WE CAN SPIN THIS THING OVER AND CHECK THE PRESSURE RATIO.

(CHUCK)>> YEAH, GIVE ME A HAND.

(JOE)>> ALL RIGHT.

(CHUCK)>> THE HEMI PISTON HAS A HUGH DOME ON IT, BUT IT FITS THE COMBUSTION CHAMBER PERFECTLY. NOW, TO CALCULATE OUR COMPRESSION RATIO, WE NEED TO MOVE THE PISTON ONE INCH DOWN IN THE HOLE. THEN WE'LL CAP IT WITH A PLEXIGLASS PLATE. AND, FILL IT WITH MINERAL SPIRITS. NOW, YOU WANT TO MAKE SURE TO ELIMINATE ALL YOUR AIR BUBBLES. NOW IT'S TIME FOR THE MATH. THE VOLUME OF A FOUR AND A HALF INCH BORE, ONE INCH DEEP IS 260 CC'S. IT TOOK 170 WITH THE PISTON IN PLACE, SO OUR DOME VOLUME IS 90. NOW, WE MEASURED OUR COMBUSTION CHAMBER VOLUME AT 165 CC'S, AND WHEN YOU SUBTRACT THE DOME VOLUME AND ADD 10.9 HEAD GASKET VOLUME, OUR COMBUSTION VOLUME IS 85.9. NOW, JUST PLUG THAT NUMBER INTO A STANDARD COMPRESSION RATIO FORMULA, AND OUR HEMI'S GOT A 14.6 SQUEEZE FACTOR.

(JOE)>> WELL NEXT COME THE COMP CAMS ROLLER LIFTERS. 'COURSE THEY'RE RIDING ON ONE OF THEIR CAMS THAT'S BEEN GROUND TO INDY SPECS.

(CHUCK)>> THE VALLEY COVER'S NEXT AND HERE'S A REAL NEAT FEATURE. THIS CENTER PART ACTUALLY COMES OUT SO WE CAN GET AT THE HEAD BOLTS AND THE LIFTERS LATER ON IF WE NEED TO.

(JOE)>> THE LEGEND HEMI HEADS HAVE IMPROVEMENT OVER ITS PREDECESSORS WITH A .350 LONGER INTAKE VALVE FROM MANLEY THAT'S A NAILHEAD DESIGN COMPARED TO THIS TULIP HEAD. NOW IT'S ALSO 2.4 COMPARED TO 2.25 INCHES ON THE STOCKER. NOW, THAT ALLOWS FOR A RAISED INTAKE PORT AND SHORT SIDE TURN FOR MORE PORT VELOCITY AND INCREASED VOLUME. 'COURSE THE EXHAUST PORT IS ALSO RAISED FOR THE SAME REASON.

(CHUCK)>> MAN, THAT'S GREAT. NOW, ON THE BENCH THESE THINGS FLOWED 490 CFM ON THE INTAKE SIDE AND 335 ON THE EXHAUST.

(JOE)>> I DON'T CARE WHAT YOU SAY, THAT'S A LOT OF AIR FLOW.

(CHUCK)>> IT REALLY IS. NOW, LET ME SHOW YOU SOMETHING. THIS IS A STOCK HEMI ROCKER STAND. ON THE LEGEND HEAD, THEY'VE BEEN CAST RIGHT IN FOR ADDITIONAL STRENGTH. OF COURSE, USING A LONGER VALVE CREATES A GEOMETRY PROBLEM AND THE WAY THAT'S BEEN ADDRESSED IS WITH A PAIR OF ADJUSTABLE SHAFTS THAT CAN BE SHIMMED INDEPENDENTLY. THEN, THE HEAD IS FINISHED OFF WITH A SET OF COMP CAMS' PACALLOY SPRINGS, LOCKS, AND RETAINERS.

(JOE)>> THE HEADS ARE ORINGED AND MATCH THIS RECEIVER GROOVE HERE ON THE BLOCK. 'COURSE THEY WORK TOGETHER WITH THIS COPPER HEAD GASKET WE GOT FROM CLARK. NOW, HERE'S A LITTLE TIP FOR YA'. USE SOME RTV AROUND THE WATER AND OIL PASSAGES TO PREVENT ANY LEAKS.

(CHUCK)>> NOW, REMEMBER. WE'RE RUNNING ALMOST 15 TO ONE COMPRESSION HERE, SO WE'VE STUDDED THE BLOCK WITH ARP STUDS. THAT WAY WE GET BETTER CLAMPING AND TRUER TORQUE READINGS.

(JOE)>> WITH OUR INDY STAINLESS ROCKERS IN PLACE, WE PUSH ON THE LASH CAPS, DROP IN OUR PUSH RODS, AND, FINALLY LASH THE VALVES.

(CHUCK)>> WELL THAT ABOUT DOES IT OVER HERE, 70 FOOT POUNDS ON THOSE HEAD BOLTS. WELL, SINCE WE'RE BUILDING ESSENTIALLY A SUPER CLASS OR BRACKET STYLE MOTOR, WE'RE GONNA GO AHEAD WITH THIS SINGLE FOUR BARREL, SINGLE PLANE SETUP. NOW, THIS ONE'S BEEN FULLY- PORTED AND POLISHED AND IT'S GOT TWO INCHES OF SPACERS HERE. NOW, THAT'S GONNA HELP US BUILD PLENUM VOLUME WHICH IS REAL CRITICAL TO FEED A 572 ENGINE LIKE OURS, ESPECIALLY IF YOU WANT MAXIMUM POWER. NOW, IT'S HELD IN PLACE WITH THESE LITTLE QUARTERINCH BOLTS HERE. YOU'RE GONNA HAVE TO BE REAL CAREFUL NOT TO OVERTIGHTEN 'EM. WE'RE TALKING 72 INCHPOUNDS HERE.

(JOE)>> WE'RE GONNA FEED OUR RACE ELEPHANT WITH THIS 1275 CFM KING DEMON CARB. IT'S GOT REMOVABLE VENTURI SLEEVES FOR ADJUSTABLE AIR FLOW, BILLET BASE PLATE AND METERING BLOCKS. AND, CHUCK, CHECK OUT HOW THEY'VE RADIUSED THOSE AIR HORNS.

(CHUCK)>> MAN, THAT'S COOL. NOW, THAT JUST ABOUT TAKES CARE OF THE HEAVY NUTS AND BOLTS. WE'LL FINISH UP NOW WITH AN ATI THREERING DAMPENER WHICH'LL KILL THE TORSIONAL VIBRATION IN A BIG MOTOR LIKE THIS. AND, WE'LL ADD A MEZIERE ELECTRIC WATER PUMP. BESIDES LOOKING COOL, IT'LL KEEP OUR HEMI COOL WITH A 35 GALLONPERHOUR FLOW RATE, AND IT'LL HOLD NINE PSI STATIC PRESSURE.

(JOE)>> HOW DO YOU LIKE THESE COOL, CAST ALUMINUM VALVE COVERS?

(CHUCK)>> WELL, THEY ARE COOL AND I TELL YA' WHAT. I'VE GOT THE IGNITION COVERED, TOO. WE'RE GONNA FIRE THIS MONSTER UP WITH THIS MSD PRO BILLET DISTRIBUTOR AND MOROSO BLUE MAX WIRES. GIVE ME A HAND THERE, JOE.

(JOE)>> SURE ENOUGH. WELL, THAT'S IT FOR OUR LEGEND HEMI BUILDUP. NOW WE GOTTA FIND OUT IF WE HIT THAT 900-HORSEPOWER MARK. WE'LL SEE YA' AT THE DYNO RIGHT AFTER THIS. (JOE OFF CAMERA)>> THAT'S RIGHT. WE'LL STRAP OUR NEWLY BUILT ELEPHANT TO AN ENGINE DYNO TO SEE IF WE PASS THE 900-HORSEPOWER MARK. AND, LATER, SOME SUPER STOCK STALWARTS OF THE 60'S ON THE NOSTALGIA RACING CIRCUIT.

[ MUSIC ]

(JOE)>> HI AND WELCOME BACK TO HORSEPOWER TV. WELL WE MADE A QUICK TRIP TO INDY CYLINDER HEADS DURING THE BREAK. AND WE'RE ABOUT TO SEE IF WE CAN GET THAT 900-HORSEPOWER FROM OUR LEGEND HEMI WE JUST BUILT. CHUCK'S BACK IN THE DYNO ROOM RIGHT NOW WITH OUR ENGINE MAN KENNY LAZZARI. LET'S SEE WHAT'S UP.

(CHUCK)>> WE'RE ABOUT READY TO MAKE THE POWER PULL ON THIS 572. NOW, WE'VE ALREADY HAD IT RUNNING A WHILE. WE GOT IT UP TO OPERATING TEMPERATURE. WELL, KENNY HERE IS RUNNING THE VALVES. HOW WE DOING?

(KENNY)>> WELL I WOULD IMAGINE THE FIRST TIME IT SUCKS IN THE HEAT, YOU'VE GOT A LOT OF VALVE LASH GROWTH. YOU REALLY HAVE TO NAIL THIS FIRST VALVE ADJUSTMENT.

(CHUCK)>> AND HOW DO WE DO THAT?

(KENNY)>> WELL, MY EXPERIENCE, I MAKE THEM .008 TIGHTER. IF IT CALLS FOR 23, I MAKE IT 15.

(CHUCK)>> GREAT. NOW, TIMING. WHAT'S THIS HEMI LIKE THERE?

(KENNY)>> TOTAL TIMING WILL BE 32 DEGREES AT 2000 RPM.

(CHUCK)>> THAT SOUNDS TIGHT. AND JETTING?

(KENNY)>> ON A NEW ENGINE LIKE THIS, YOU ALWAYS JET UP FIRST. YOU NEVER JET DOWN.

(CHUCK)>> THAT WAY WE CAN SNEAK UP ON IT. WHAT DO YOU SAY WE BUTTON THIS THING UP. I WANNA MAKE SOME NOISE. [ ENGINE REVVING ] WELL, IT'S THE MOMENT OF TRUTH.

[ ENGINE REVVING ]

(JOE)>> WHOO! 940 HORSEPOWER. THAT'S EVEN MORE THAN WE EXPECTED. BUT, KENNY I KNOW YOU'VE GOT ANOTHER INTAKE THAT WANNA TRY THAT'LL GIVE US EVEN MORE. TELL ME ABOUT IT.

(KENNY)>> WE'VE GOT A BRAND NEW, STATE OF THE ART TUNNEL RAM WITH TWO BIG 1050 CARBURETORS. IT'S A FIRST NEW DESIGN TUNNEL RAM FOR HEMI IN 25 YEARS.

(JOE)>> WOW! LET'S GIVE IT A SHOT.

(KENNY)>> YOU GUYS READY TO TRY OUT THIS TUNNEL RAM?

(CHUCK)>> YOU BET!

(KENNY)>> THAT 940-HORSEPOWER'S HISTORY! [ ENGINE STARTING ] [ ENGINE REVVING ]

(CHUCK)>> HEY, THIS IS INCREDIBLE. WE JUST MADE OVER 1030-HORSEPOWER!

(JOE)>> YEAH, WE SURE DID. HEY CHECK THIS OUT. 840 FOOT POUNDS OF TORQUE.

(CHUCK)>> NOW, I DON'T CARE WHAT YOU SAY, THAT ELEPHANT IS ONE POWERFUL PACHYDERM.

(JOE)>> YOU GOT THAT RIGHT. WELL, WE'RE GONNA PACK UP AND HIT THE ROAD. BUT DON'T YOU GO ANYWHERE. THERE'S MORE HORSEPOWER TV COMING RIGHT UP. [ MUSIC ] (JOE OFF CAMERA)>> JUST AHEAD, RACING INTO THE PAST, NOSTALGIA SUPER STOCK STYLE. AND LATER, SOME NEW HOT STUFF FROM THE HIGH PERFORMANCE AFTERMARKET. STAY TUNED.

[ MUSIC ] (JOE OFF CAMERA)>> THEY WERE FAST TIMES - THE EARLY 60'S. BACK WHEN THE BEATLES WERE KINGS OF ROCK AND MARILYN WAS STILL QUEEN OF THE SCREEN, AND SUPER STOCK DRAG RACERS RULED THE STRIPS. AT THE 1963 WINTER NATIONALS, A DODGE GRAND CHARGER WON THE CHAMPIONSHIP WITH AN ET OF 12.44 SECONDS AT A NOT SO BLINDING SPEED OF 115 MILES AN HOUR. [ MUSIC ]

(JOE)>> FOR MOST OF US, THE 60'S AND THOSE SUPER STOCK CARS ARE ALL MEMORIES NOW, BUT NOT QUITE. YOU SEE IN THE NOSTALGIA SUPER STOCK CLASS, WELL THE BODIES AND THE MOTORS ARE THE REAL DEAL. THEY'RE NOT AS FAST AS PRO STREET, BUT, HEY THEY'RE PRETTY QUICK TO BRING BACK MEMORIES. [ ENGINE REVVING ]

(BRUCE)>> IN 1963 WHEN THEY BUILT THIS CAR, IT WAS BUILT WITH ONE PURPOSE IN MIND. THAT'S TO GO FAST AND GO STRAIGHT AND HAVE A GOOD TIME WITH IT. [ ENGINE REVVING ] (JOE OFF CAMERA)>> NOSTALGIA SUPER STOCK CARS ALL CARRY THE SAME BODY STYLES AND ENGINES AS THEIR FAMOUS FOREBEARERS. ALL HAVE THE FACTORYOFFERED, ALLMOTOR BIG BLOCKS THAT MADE THEM LEGENDS IN THE MUSCLE CAR ERA. WHILE SOME JUST LOOK THE PART, GENE AND JUDY EGBERT'S '64 GALAXY WAS A "B" AND "C" STOCK WINNER. TODAY ON THE NOSTALGIA CIRCUIT THE PURPOSE OF COMPETITION HAS GONE THROUGH CHANGES SINCE THE OLD DAYS.

(GENE)>> FUN. THAT'S WHAT IT'S ALL ABOUT. IF I WIN, THAT'S AN EXTRA. IT'S REALLY PRIDE MORE THAN ANYTHING, TO SHOW THE CARS LIKE THEY WERE, TO GET KIDS INTERESTED, LIKE IT WAS IN THE 60'S AND 70'S, AND KEEP THE HERITAGE GOING ON. [ MUSIC ] (JOE OFF CAMERA)>> ONE OF THE KIDS GENE WON'T HAVE TO SELL IS JEFF DAY FROM CANTON, OHIO. JEFF COMPETES IN THE NSS CLASS IN HIS '64 PLYMOUTH FURY, BUILT LONG BEFORE HE WAS EVEN BORN.

(JEFF)>> I JUST LIKE THE OLD CARS. THEY'RE NEAT, THEY'RE WHAT ORIGINALLY STARTED RACING AND STUFF. A LOT OF THESE NEWER CARS WITH NITROUS, IT MEAN IT'S NOT HOW RACING WAS, IT'S HOW RACING WILL BE. (JOE OFF CAMERA)>> NOSTALGIA SUPER STOCK ET'S RANGE FROM THE TENS TO THE MIDTWELVES. AND WHILE THAT'S SLOW COMPARED TO TODAY'S BLOWN OR NITROUS CARS, THAT'S STILL A HANDFUL OF FUN. AND IF YOU LIKE UNIQUE MECHANICAL CHALLENGES, THIS CLASS COULD BE MADE FOR YOU.

(BRUCE)>> YOU GOTTA WANT THESE CARS. YOU HAVE TO LIKE 'EM. YOU HAVE TO TRY TO PRESERVE HISTORY AND TRY TO KEEP THE FLAME GOING. IT'S JUST INTERESTING. THEY'RE HARD CARS TO KEEP RUNNING. THEY TAKE A LOT OF WORK. THEY'RE REALLY PARTICULAR AND METICULOUS, BUT THEY'RE FUN. (JOE OFF CAMERA)>> SO JUST PUSH "D" FOR DRAG RACING, MASH THE GAS, AND YOU'RE OFF RACING TOWARD YESTERYEAR WHEN 409'S, FAIRLANES, AND BELVEDERES WERE KINGS OF THE STREET. IT'S A MAGIC MUSCLE CAR ERA THAT LIVES ON THANKS TO AN ELITE CLASS OF NOSTALGIA SUPER STOCKERS.

(JUDY)>> THIS IS THE BEST CLASS BECAUSE WE'RE NOSTALGIC JUST LIKE THE CARS.

(ANNOUNCER)>> NOW HORSEPOWER'S HOT PARTS, BROUGHT TO YOU BY SUMMIT RACING EQUIPMENT. YOUR SOURCE FOR HIGH PERFORMANCE PARTS FOR 30 YEARS.

(CHUCK)>> WHEN I WENT TO FINISHING SCHOOL THEY TAUGHT ME HOW TO BE MORE "TACHFUL". AND, WELL, THIS IS WHAT I CAME UP WITH. IT'S THE PRO TACH V FROM MALLORY. NOW, IT'S GOT A FIVEINCH FACE WITH LARGE NUMBERS AND A RED POINTER FOR EASY READOUT. PLUS, IT'S GOT A MEMORY FEATURE FOR HIGHEST RPM. YOU ACTIVATE IT WITH THIS HEAVYDUTY ROCKER SWITCH. NOW, RACING VIBRATIONS DON'T AFFECT IT. YOU CAN MOUNT IT IN ANY POSITION. PLUS, IT'S COMPATIBLE WITH JUST ABOUT ANY KIND OF IGNITION. IT'S ALSO COMPATIBLE WITH YOUR BUDGET AT ABOUT $170 BUCKS.

(JOE)>> HERE'S SOMETHING THAT'LL ADD TO YOUR AIR FLOW WITHOUT DEPLETING YOUR DOLLARS. THESE POWER FILTERS FROM ACCEL ARE AN EASY DROPIN REPLACEMENT FOR YOUR STOCK AIR CLEANER ELEMENTS. AND, THEY HAVE TWO STAGES OF FILTRATION. THIS OUTER, COARSER LAYER OF FOAM IS YOUR PRIMARY FILTER. AND, THIS FINER INNER LAYER WILL STOP PARTICLES DOWN TO THREE MICRONS IN DIAMETER. AND, THEY'RE REUSABLE AFTER YOU WASH 'EM AND REVITALIZE 'EM WITH THIS FOAM FILTER OIL. NOW YOU WON'T HAVE TO REVITALIZE YOUR BANK ACCOUNT. THEY'RE ONLY ABOUT $20 BUCKS.

(CHUCK)>> AND, HERE'S SOMETHING THAT'LL HELP YOU FIVELITER FORD FANS ACCOUNT FOR MORE HORSEPOWER. TRICK FLOW'S NEW EFI INTAKE IS A COMPUTERMODELED PIECE THAT'LL GIVE EXCELLENT BOTTOMEND TORQUE WITHOUT SACRIFICING HIGHEND HORSEPOWER. NOW, IT ALSO PREVENTS FUEL STARVATION ON THE FRONT CYLINDERS, A PRETTY COMMON PROBLEM AMONG EFI FORDS. TO TOP IT ALL OFF, IT'S ALSO POWDERCOATED FOR GOOD LOOKS. AND I'LL TELL YA' SOMETHING ELSE THAT LOOKS PRETTY GOOD. THE PRICE AT ABOUT $395.

(JOE)>> WELL HERE'S SOMETHING THAT LOOKS GOOD AND WON'T COST YOU ANYTHING. OUR SHOW NEXT WEEK. [ MUSIC ]

(JOE)>> WE'LL SHOW YOU HOW TO MAKE NEARLY 20 EXTRA HORSEPOWER IN A STOCK '91 FIREBIRD. IT'S A HIGH PERFORMANCE TUNE UP THAT INCLUDES A NEW MANIFOLD, IGNITION UPGRADE, UNDERDRIVE PULLEYS, AND A COMPUTER CHIP. WE'LL SHOW YOU HOW TO DETAIL YOUR TRUCK IN NO TIME FLAT, AND TAKE YOU TO A NEW HOT ROD HANGOUT DOWN IN ORLANDO. AND REMEMBER HIGH PERFORMANCE FUN IS WHAT THIS SHOW'S ALL ABOUT. WELL CHEVY BOY I GUESS YOU WANT ME TO DRIVE THIS THING?

(CHUCK)>> NO LAST TIME WE HAD A CORONET ON THIS SHOW YOU GOT TO DRIVE. I'M DRIVING THIS TIME. WE'RE GONNA TEAR UP THE TARMAC AND I DON'T CARE WHAT MY CHEVY BUDDIES SAY.

(JOE)>> I WON'T TELL THEM. WHOA, 440!

(CHUCK)>> ALL RIGHT HERE WE GO. YOU READY?

(JOE)>> I'M READY MAN! WHAT DO YOU THINK IT'LL DO?

(CHUCK)>> I DON'T KNOW. LET'S SEE IF WE CAN GET IT OUT HERE AND GET IT UP ON THE TIRES. HERE WE GO, READY?

(JOE)>> YEAH! [ ENGINE REVVING ] [ MUSIC ]

(NARRATOR)>> HORSEPOWER TV IS AN RTM PRODUCTION.
