Big block Engine question

while Buick, Olds, & Pontiac all made 455's, they were all different engines unique to each division. Therefore only the Pontiac would be a direct bolt in. Pontiac was probably the best of the three anyway, although Buick did produce a few very impressive motors. - Gary

In a word... Yep. Buick and Olds and Pontiac 455s are all different. Probably easier to find the pontiac, I'd think. As far as performance, the Pontiac has the advantage in available parts and cost.

Off topic a little... but I remember several years ago.... I had browed my Dad's 455 Bonneville while my Mustang was in the shop for a trans rebuild.... Anyway... I pulled up to a red light and there was a Z28 in the next lane. (The Z's were only running 305's at the time.) The guy in the Z sat there revving the motor.... I sat there and thought well.... I think this old tank my very well be able to win this. The light changed and the Z's lost really really badly. That 455 had put that old Bonneville ahead by several car lengths!!!!!!!!!!!!!!!

Since Pontiac V8's aren't big or small block, ya there are differences :).

Any of the 455 engines that are BOP can be made to run. It's all in your brainpower and your wallet.

I have seen Olds 455 that would smoke a Chevy 454 alive. I have seen Pontiac

Sure, if you got a SD455 out of something over a 455 in a luxo boat Oldsmobile, there is a REAL difference there. LOL.

If you've got a 455-SD, then you've got a goldmine! Not many of 'em are left. (Right Dennis!)

I want a '73 455-SD so bad it makes my heart weep just thinking about the fact that I may never get to even ride in one.

Why only a '73? I would imagine the superduty was made more years than just in '73.. or am I wrong?

I believe the the SD version of the 455 was available in both '73 and '74. IMHO the '73 was a MUCH better looking car.

'73 and '74. 1974 was far more popular and nice condition '74 SD-455 T/A's can still be had for around $20,000.

Should have bought a '73 Super Duty instead of the '01 Formula. Cost the same and the '73 appreciates in value :-)

But the 01 is faster. ;) Seriously, I bow before a 455SD, but my stock 01 LS1 Trans Am would keep up with a stock SD in the 1/4 and blow it away at the top end. That's why I bought my 80 - I want one of each. And I abuse them way too much to be worried about collector car status - besides, that only applies if you're selling them.
