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!

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.

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

This is what it was about before the LS engine!

@bmstylee 11 ай бұрын

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.

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.

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.

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

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.

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

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

@@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 25 күн бұрын

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.

How much would this build cost

@classified70 7 ай бұрын

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
