426 MOPAR BUILD-UP & DYNO, BLOOPERS

Hey, today we're gonna build a big inch big horse small block for you. Mopar

fans. Now you're gonna have to excuse me. I'm late for work

today on horsepower TV. It's Mopar

Mayhem on the show as we build a 426 cubic inch small block with new state of the art heads, high performance carb and intake. Plus we'll

dyno this baby as we shoot for 600 horsepower at the crank.

Plus you asked for it. More horsepower bloopers our best of the worst. Uh That felt good.

So hang on for horsepower TV.

Hey, come on back.

That's good.

Hi, welcome to the horsepower shop and some

Mopar motor mayhem.

If you've been watching us for several years, you might recognize this 70 duster that we built up on the show. Now, it's a tense streeter runs on pump gas cranks out 670 horsepower. Thanks to that 500 cubic inch indie cylinder heads big block. Now, since then, this baby's been known to win several street car shootouts

next

star. 69 Holly Roadrunner. Now it too uses an Indie cylinder head big block, but this one is 542 cubic inches and cranks out 700 ft pounds of torque.

Now, this original four speed car was restored by John

Balo of Muscle car restorations with a little bit of help from year 1426 has been a magic Mopar number for years, both with the max wedge and the

hemi.

Well, today we're gonna build a better rat trap and our own 426 by pushing the A engine envelope to the extreme.

Now, the A engine is Chrysler's small block that's either 340 or 360 cubic inches.

Now, you guys that have been working with these engines know of their inherent deficiencies. For instance, the stock lifter boards are 59 degrees and cylinder head ceiling is limited by only 10 head boats good points. Now, to get our 426 cubic inches, we need both a big bore and a big arm. So we're starting with Mopar performance R three Siamese bore cylinder block. Now, it comes with additional head bolt holes and four bolt mains. Of course, later on, we're gonna show you some cylinder heads that make use of these extra head bolt holes for improved cylinder ceiling while still retaining those 59 degree lifter bores. Now, the block has been prepped by indie cylinder head and we've already installed a RP head and main studs.

Our crank here comes from mo par performance. It's a four inch stroke cast crank with internal balancing. Now we've hung a set of eagle 3d rods that are stock a in length on a set of weo

pistons with four and 1/8 inch bores. By the way, the small dome here gives us a 12.5 to 1 compression ratio.

This setup uses 1/16 inch Molly face rings. They come from Speed Pro and

I guess we'll get started but dropping in this crank,

we torched the main studs to 85 ft pounds on the inside, 80 on the outside.

The pistons and rods are next.

Now, make sure to use some of Eagle's Rod boat lo before torquing these down to 63 ft pounds.

One of the keys to making this combination work is the cam shaft. And our 426 uses an off the shelf grind from comp cams. Now, this is a 610 lift solid flat tappet piece and hey, we're gonna use some new technology to get roller cam performance out of this flat tappet design.

That's also gonna allow us to retain those 59 degree lifter boards and make use of those extra cylinder head boat holes that we told you about earlier.

The shoe back lifters have a silicon nitride coating here on the base. It's one of the hardest materials known to man.

Now, what that's gonna do is eliminate camshaft wear completely and allow us to run a lot stiffer bow spring. Now, we've got our set at 200 pounds at the seat.

After lubing the camshaft with regular motor oil, just slip it in place,

then install the cam plate, making sure the retainer bolt with the oiler hole in it is installed up here.

Well, the timing set is next and we're using a roll master that uses billet gears and multiple keyways on the bottom sprocket here. Now, that's gonna allow us to advance or retard our cam shaft.

Now we're gonna set ours at two degrees retarded, which ought to help our horsepower figures on a big inch engine like this one.

The oiling system is the lifeblood of any engine and to keep ours alive, we're using this high volume pump with a Milon

pickup plus a seven quart street strip pan here from Charlie's. Now, the neat thing about this pan is it eliminates any need for this ugly old seal because Charlie has tightened up the tolerances and, well, all that's required is the thin beat of silicone. Well, let's get this thing on now.

There we go. 33 ft pounds.

Now, the beat of silicone.

All right. That's it for the oiling system. What do you think? Hey, this short blocks looking pretty good.

Now, the last piece that we're gonna bolt up is this A T I two ring super damper? Now, we like it because if, and when we need to, we can send it back and have it rebuilt.

Well, what we need to do is take a break right now, but we'll be back to jump on the top end of our rat trap small block and later take it to the dinos to

stay with us

later in the show, some memorable moments. We'd like to forget in the horsepower shop and beyond. So stay with us

this

thing.

Hey, welcome back to the shop and our 426 small block build up.

Well, so far we filled our short block here with a Mopar performance Stroker crank Weis

go pistons on a set of eagle rides and a comp cams flat tap at camshaft. Well, after buttoning up the bottom end with our Charlie's oil pan, I guess we're ready to look at our heads.

Hey, if we're gonna build a better rat trap, we're gonna need to crank out six 100 horsepower or more and to do that, we need to move a lot of air both in and out of the engine. Now, the Edelbrock performer RPM is probably one of the most popular aftermarket heads for the small block Mo

Park.

Any cylinder head starts with semi finished Edelbrock heads then takes them to the next level by relocating the intake push rod locations. Now that allows them to enlarge the port openings and follow up with their super modified port job. Now these things are gonna flow 275 CFM past the 2051 60 valves.

Well, earlier, we told you about a head that would allow us to use those extra bolt toes for better ceiling and allow us to run up to 12.5 or higher compression ratios without blowing a head gasket. Well, here it is, it's a new casting from

cylinder head with these extra bosses for those bolts.

The intake volume is 210 CCS and they flow, get this 330 CFM. Of course, the valves are larger too 2 101 650. Now, even with these extra bosses, the heads work on any 340 or 360 block. Now, later today,

we're gonna try out a pair when we head to the engine, dyno.

Hey, those are some pretty impressive numbers. Now, I've already dropped the lifters in and also dropped on one of the cylinder heads. Now to further ensure that we have good cylinder ceiling. We're using these

fro head gaskets with an Integra O ring.

Now, this baby is ready to torque down and we're gonna crank each one of the studs to 95 ft pounds.

All right. Well, the rocker assembly we're using compensates for the relocated push rides

with a 150 offset intake rocker say one used on the 440 big block. Now, after we get them laid in place, we'll torque them down to 35 ft pounds. Then lash the valves,

we're gonna match those Edelbrock heads with their single plane victor intake. Now, this one mounts a 1025 CFM race demon carb.

This carbs got plenty of air flow to feed our 426 and

also give us a good booster signal for Chris throttle response. Now it's also got down leg boosters and interchangeable venturia so you can tune the carb for your own application

before we drop on those valve covers. Let me show you something. It's important to break in your valve train properly because after all, you don't want a dry start that could damage your expensive components.

So we're gonna use some of the slip coat spray from comp cams on all the rockers, springs and shafts.

That way, we'll have a nice gel coating on all the valve train parts to protect it during the first critical minutes of start up.

High horsepower engines generate more than their fair share of heat. So you need to keep a lot of coolant circulating through the system. Now, we're gonna use this Missouri Electric water pump that pushes 35 gallons per hour.

The installation starts with the backing plate first

followed by the pump

with 12.5 to 1 compression and a power band up to 7500 RPM. Well, we need a good reliable ignition. So we're dropping in this pro billet distributor from MS D along with a set of their 8.5 millimeter superconductor wires. Now, this will ensure compatibility with that MS D ignition box that's already bolted up at the

dyno now, we hate to bolt on out of here, but we need to head on up to the dyno ourselves. We'll meet you there right after this short break.

All right, welcome back. While you were gone. We made a trip up here to Indy cylinder head for a little

dyno time.

In fact, I guess we're getting ready to see if we did build a better rat trap with that 426 Mopar small block. Well, the engine's already on the

dyno and, and I heard him warming it up but just a little bit ago. So let's go check it out. All right.

Well, if you remember we started with a mobile

performance Siamese bore block and Stroker crank, then we filled it with Weiss co pistons and capped everything off with a set of Edelbrock Indie cylinder heads and a Victor intake. Well, now, what do you say we bring this rat killer to life?

Yeah. Sounds pretty good.

Well, this is Kenny Lazar, the resident engine builder here. And, well, I guess we're ready for a run. If it's warmed up, it's warmed up at two, then let's see what we got. All right.

Ok. That's a pretty stout passing this little rat killer. But, uh, how about the numbers? 600 horsepower, 565 ft pounds of torque when a torque is that close to the horsepower? It makes a wild street strip engine. Yeah, I'll say. But, uh, how are you gonna get more horsepower out of this thing.

We'll show you how. Ok.

Hey, I'm way ahead of you guys. Now, these Edelbrock Indie cylinder heads are about as good as it gets for a street strip engine,

but an engine will only run as good as its intake port. And, well, that's where these 210 CC ports on these Indie 3 60-2 heads come in.

Of

course, those oversized runners require the use of these offset rockers too.

Yeah, Chuck, we just came out with his intake to go with these heads. It's a high rise featuring a deep plenum and extended runners. You can't make it any better than this. Well, let's throw it on there and make another pull.

Hey man, check out the print out on that run 665 horsepower at 6900 RPM. Well, the new heads and intake and definitely worth 65 horsepower, but check it out. The torque stayed about the same, moved up the scale about another 1000 RPM. That's stout. I'll tell you what neither configuration.

This is a motor that'll trap rats on the street or strips. Well, speaking of the street man, we need to hit it again. Get back to the studio and we'll see you there.

Don't go away. The worst is yet to come. Horsepower TV, bloopers backed by popular demand.

Hey man,

I've been thinking,

oh, no, not again. Why.

But do you remember that time that you drove the yellow Roadster here into the studio and he almost drove over our cameraman Greg.

Oh, sorry. Very funny. But while we're at it, do you remember the time that it took you about uh 20 tries to get an alternator net started? Remove the old pulley,

install the new one

and reinstall

and reinstall the nut

and reinstall the nut.

And this

is, no, I don't remember that. Well, I do and so do many of our viewers. In fact, everywhere I go, people wanna know if you've learned your righty tidy lesson or not.

Well, what we both learned is that what you like best is when we're at our worst. Now we're a couple of gearheads. But hey, we're also a human. So if it's bloopers you want, it's bloopers, you'll get

right, you are. And here it is volume five of the best of the worst of horsepower TV.

They were chuck That all makes great sense. And obviously the chain and belt each had things going for them. But

how do you choose the, uh

you choose your lines carefully?

Hey, we're gonna use some new technology to get roller camp performance from this flat tap of design.

Now that allow us to retain the use of those 59 degree,

we're gonna use some new technology to get roller camp performance from this flat Tappet design.

Now, that's gonna allow us to use that 59 degree Luke bore anchor.

Hey, we're gonna use some new technology to get roller cam performance from this flat tap at design. Now that's gonna let us use those 59 degree board lift.

Shut up.

You ain't rolling on that

here in the pits of the racetrack. Drivers can learn a lot about the hardware that makes them go faster. Sometimes the experience behind the wheel can lead to building flow.

Ladies and gentlemen, welcome to the first inaugural Miss It. Inaugural,

inaugural,

that word. The word,

inaugural,

inaugural,

inaugural

inaugural plate. Two of them. One with chicken, one with shrimp.

Yeah. Now the motor

mass that we're using come from energy suspension and

or they're made with urethane here to help resist the effects of gas, oil and chemicals. Plus

that was

close.

Now, if you travel to the car show, you can ride in the lap of luxury with soft leather seats, uh entertainment center.

In fact, all the comforts of home.

I'll say

you said

we

could

find some car.

I just lost it. I'm

sorry,

I just lost it.

Go back in there and do some more.

Damn, I just got a hurricane. Where you going?

Hey, hey Joe,

you got your feathers

now while you were gone. I went ahead and finishing the preload on our pin. So now we're ready for our third pin bearing

and the retainer.

Uh Oh, that felt good.

It comes slow,

man. I

wish we had this kind of room for our Mustangs Motor.

I tell you this is a big engine bay. How are we looking at

forward here for

little folks here?

Oh, man,

it's f,

well, hey, I'm glad to see the tape editors decided to leave a few of your not so great moments in there this time. Well, of course, uh I did all that on purpose just to make you feel good. Sure you did now, hey, what I feel good about though is letting them see a little bit about what really goes on around here. Yeah, me too. Well with or without bloopers, hot parts is coming up next.

Horsepower TV

S hot parts. A close up. Look at the latest in high performance hardware.

Hey, nobody likes to get the shaft. But if you've got a 5 L Ford, well, here's a shaft that you might wanna get.

Now these shaft mounted roller rockers from Harlan's Sharp boat ride up and they'll clear stock valve covers with only minor modifications.

The three quarter inch shaft here mounts a pair of adjustable rockers to stabilize your valve train and eliminate the need for shims. Of course, if you want a set of them, you'll have to eliminate about $500 from your budget.

If you've got an LT one

cfour vet, here's a cool way to upgrade your exhaust course of performance has crafted their cat back system from stainless steel for high power and long life. This free flowing kit comes with the pipes, mufflers and clamps. You need to give your Corvette a cool new sound without any residents inside the cockpit. Now, if you want one of these for your

cfour, you'll have to plop down about 10 C notes

whether you've noticed it or not. Well, I finally found a diet that

works for me. And so is this tack from Proform? Now, we're both 30% lighter and thinner front to rear. Of course, for the tack. That means uh more clearance and an easier installation.

Now, it uses state of the art touch controls and has features like memory recall and this compact shift light indicator.

Now, if you want one, well, you're gonna have to shift about $100 out of your bank account. Oh, you forgot to mention you're 30% lighter because most of it's hot air.

Well, there's nothing to light about our show next week. Here's a look at it.

We'll drop a 350 small block in our Chevelle chassis backed up by an automatic overdrive trance.

We'll also add the pulleys and a reverse water pump bid from the intake to the exhaust. We'll show you how to get the most horsepower on a limited budget.

Plus a profile on a racer who went on to put his name on some of the hottest parts in high performance.

And remember high performance fun is what this show is all about.

Hey, I just thought of something fun.

Did you get the motor to take back from Mindy Syder

here.

No, I thought you had it.

Do I look like I have a Mopar

motor with me? No,

you were supposed to load it in your truck. Your Chevy truck. I was driving
