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

Pontiacs are on the war path! We're going to get 600 horsepower on pump gas from a 455 with forged pistons and 1050 CFM carb. We even put it to the test on the dyno!

Gotta love the sound of the Pontiac V8.

[@user-xt3ot1xu1b]

Thats one happy dyno.....

[@michaeljoeallen9412]

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

[@Ultegra10SPD]

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

What an immaculate workshop ! Vèry tidy indeedy !

[@johnbehneman1546]

That is one badass Pontiac 455

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.

[@gpoetx]

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

[@johnbehneman1546]

Thank you so much

[@johnbehneman1546]

Great daily driver motor

[@malamri424]

That's a big cam! 302°

[@davidsutton9148]

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

[@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.

[@elijahweddle3092]

Custom cam is really an off the shelf part wtf😂

[@billhendon1017]

Awesome!

[@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

This show is 25 + years old !

[@Fuckstupidlibtards]

Pretty rad. Blast from the past

[@FINfinFINfinFINfin]

What was the torque number?

[@johnbehneman1546]

Suggestion: Aftermarket big black.

[@FINfinFINfinFINfin]

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

[@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.

[@joehiden7475]

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

[@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]

🤣🤣😂😵‍💫

[@taztaz728]

hollywood tv garage.oh how clean.😂😂

[@Roboticgladiator]

Which grade pump gas?

[@xander-R467]

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

[@hopebrowning6300]

Nah..yea more hp out of the 400 but can't beat the 455 where it matters, torque!

[@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

[@robertwoodbury4666]

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

no breaking the cam in?🤷🏼‍♂️

[@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.

[@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

[@nimnow8060]

? Chev LS6&7 know not Buick but long ago

[@klausschreyer7062]

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

[@klausschreyer7062]

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

[@DiesalAZ]

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