How To Build A Hot Pontiac 455 for Pump Gas - Horsepower S4, E20

[@ClassicGBodyGarage]

RIP Joe 🙏

[@CJColvin]

Gotta love the sound of the Pontiac V8.

[@michaeljoeallen9412]

That sounds great!!🎉 612hp on pump gas. 😮

[@johnbehneman1546]

That is one badass Pontiac 455

[@dennistaylor5052]

Billet main caps and ARP studs...back in 2000 the caps were $105 ea and they didn't make a billet rear main, at least Butler didn't offer them. You left out a bunch of important stuff, tap oil galley plugs behind the timing chain (which you did), don't screw them to deep they'll obstruct the oil galley, out to far they hit the timing chain. To center the dampener you have to remove the centering sleeves in the block for the timing cover to move up towards the cam if the block was line honed. If the lifters are solid roller did you tap and install oil restrictors in the lifter bores or did you use restrictive push rods? I didn't know High Volume oil pumps were available for Pontiac, thought they only offered High pressure pumps, did you change to a heavy duty oil pump drive shaft to go with the pump?...just to mention a few. I realize your time is short on the show, but with Pontiac these things are more important than Lubing the mains and setting the crank.

Wasnt the guy portin’ iron heads in the shot then later they said they had ally jobs going on? Hmmmmm. -U10

So what Inspector Gadget

[@FINfinFINfinFINfin]

What was the torque number?

[@jackmigge1624]

What an immaculate workshop ! Vèry tidy indeedy !

[@davidsutton9148]

Nice motor, I wonder what it’s going in? Hood clearance might be an issue with that intake manifold.

[@GeneralLao]

Thats one happy dyno.....

[@InstructorRandy]

This is what it was about before the LS engine!

[@bmstylee]

Yes. Then the LS, late model Hemi, and Coyote came along and made everything else completely obsolete. Use the Holdener theory. End gap + cam swap + boost = big power.

[@maynardreed4036]

I'll still take my pontiac 455 over any ls engine.

[@Aliceinchains1234]

all pussy engines that make fuck all of torque. If you want real power, you gotta go with a PUSH ROD V-8.@@bmstylee

[@chriscarbaugh3936]

@@maynardreed4036why do you need more 😎

[@gpoetx]

WHy on earth would you use an old fashion rope seal for the main? Viton seal is so much better

[@elijahweddle3092]

Custom cam is really an off the shelf part wtf😂

[@flexjay87]

This show is 25 + years old !

A couple of actors that are clueless.

[@malamri424]

That's a big cam! 302°

[@xander-R467]

I would prefer a 400 Pontiac stroker than the 455... But nice parts mounted on and today extreme expensive to built...

[@xander-R467]

@hopebrowning6300 400 stroke to 467 and up was meaning... The 455 is not a good basic for a stroker... That was what I wanted to say

[@happycat0411]

Just find some old used 7K3 heads from an early 70s Pontiac 400 and these D port heads will give you about 9.5 compression on a Pontiac 455!

[@jlh8296]

No windage tray? That cost some Hp in a long stroke engine for sure. Most 68-72 pontiacs came with either a full lenghth factory windage tray or later a 4/5 th's length tray.

[@robertwoodbury4666]

Nice hair piece chuck try flex glue to hold it on your head next time

Great daily driver motor

[@taztaz728]

hollywood tv garage.oh how clean.😂😂

[@corporalclegg914]

06:24 the dude put the oil pan on upside down. it’s supposed to be on the bottom of engines, not the top…that’s where the gasoline. he didn’t even fill the oil pan up with oil before improperly mounting it to the top. weird.

[@caspar0777]

🤣🤣😂😵‍💫

[@franciscooper.retired]

You don't have to yell we're not deaf.

[@johnbehneman1546]

Suggestion: Aftermarket big black.

[@FINfinFINfinFINfin]

Big black what? Are you trying to tell us something?

[@taztaz728]

hmm How can their hands stay so clean?and all that free expensive tools

[@joehiden7475]

This looks like it will not fit in a Trans Am 1973 0r 1974 with a shaker hood. Is this the case?

[@klausphx]

Can use Edelbrock Torker II Open Plenum Fits Squarebore or Spreadbore Carb or Throttle Body Injectuon I run Torker Intake on my 76 Trans-Am 455 Shaker just fits Hood Clearance is fine. But do not use thick Spacer between Carb and Intake I use Thin Gaskets with .050 Aluminum Heat Shield. Performer RPM intake Dual Plane Excellent Intake Manifold but I hear you have to Modify Air Cleaner Lower Housing for Trans-Am Shaker to Hood Clearance . Performer Intake good for Stock Engine but weighs a lot less than Stock Iron Intake.

[@Roboticgladiator]

Which grade pump gas?

[@johnbehneman1546]

Thank you so much

[@genfiveten595]

[@MrWarwickbass]

1:50 no torqueplate ?

[@keithhastings4092]

They had me at rope seal…

[@dennistaylor5052]

@@keithhastings4092BOP offers a 1 piece seal, if that's an aftermarket crank, it doesn't have the crosshatch for the rope seal. If it does have the crosshatch you can't get it to seal with a 1 piece or a 2 piece seal... ask me how I know🤨

[@jlh8296]

Pontiacs don't have 5 head bolts per cylinder, causing distortion, so not as critical to have them torque plate honed like a chevy sb or bb.

[@VanoyBrown]

4 bolt mains ?

[@billhendon1017]

Awesome!

[@conniechamberlain6586]

how much torque?

[@1arritechno]

Most important for any performance 455 is having large Oil Coolers up front. These monsters produce too much HEAT and run too hot in Summer, without Oil Cooling.

[@apachebill]

Live in Texas. Have never run a cooler and my mill runs 190° with the AC on in the 110° heat. Never have run a cooler. If they’re getting that hot something is wrong.

[@spyder2383]

Nothing like running a 1050 dominator on pump gas. Smh

[@taztaz728]

no breaking the cam in?🤷🏼‍♂️

[@elebeu]

It's a roller cam.

[@flmggreedyy6521]

How much would this build cost

[@classified70]

Just building one right now, depending on what quality of parts you throw at it but not cheap by any means, I'm already at $14k including machining and labour and I'm sure there will be more to come

[@DiesalAZ]

i would prefer these guys had grease under their fingernails. Nice build though

[@frankartale1026]

I always heard a single plane manifold was not good for a Pontiac Street engines. Unless using injectors at the port on each cyl. I'm not saying this is true but that iv'e heard it alot. Back in my day over 30 years ago.

[@spyder2383]

I started running a single plane in 1978, no problems. Although these days I decided to just do tripower. But I don't race anymore.

[@frankartale1026]

@spyder2383 i bought 403 t/a in 1991 and it had a single plane on it. What a sled. I was a kid and knew nothing. Even with a 3.08 posi in place of the 2.56 i had. The car ran 15.8. I ripped it out a put a built 400 and it ran high 12's. Those were good times

[@spyder2383]

@@frankartale1026 you needed more gear, tbf I ran 4.11's on a 4 speed.

[@frankartale1026]

@@spyder2383 oh dont worry, i changed the heads from 6x to #16 swapped the cam. Put 3.42s in it and never touched the qjet from my original tune with 72 jets and CV secondary rods and it ran 12.20 on street tires.. My next bird was a 400 4speed with 3.23's a special super t10 with a 2.92 first gear and a 1.91 second. From s&k speed. It also ran low 12's on street tires. I could never deal with 4.11s . I was turning 3000 at 70 with 3.23s. That drove me nuts 😁 i had many of these cars. But only these 2 were fast. I also had 2 81 4spd t/a's with 305 and 3.42 standard. I put a 350 in one and it ran high 13's. That car was screaming at 70. To me anyway 3200rpm. That is too much for me

[@klausphx]

What's Torque on Pontiac 455 Build. Oh it's Horse Power TV don't know how to Measure Torque on your Dyno

[@TAWS-wq3hx]

Every Pontiac Ive seen with 600+ HP has had near 700 lb ft of torque

[@grapeknutz]

Chevy rods? it changes the rod stroke ratio and makes it worst.

[@spyder2383]

Nope, I'm running bbc rods in my 461.

[@nimnow8060]

? Chev LS6&7 know not Buick but long ago

[@klausphx]

Those Engines you put in Camaros not Gen 1 or 2 Trans Ams or any Pontiac older than 1981.
