Buick 455
Wondering how a '70 Buick 455 compares with an Olds of the same year. And whether I could drop that Buick 455 into my '72 Cutlass Supreme, which currently has an original 350 motor and 350 trans.

The Buick is comprable to the Olds, but is different. As your car is an A body, you would have to treat it like a Skylark or GS and use the frame brackets and engine mounts for a Buick. It is basically a bolt in with minor wiring and exhaust changes (you need to use the Buick exhaust manifolds). Your transmission should bolt up, but I think you'll need the Buick torque convertor.

Thanks, All, for that info on the Buick 455. I saw some posts elsewhere comparing the Pontiac, Buick, and Olds versions of the 455. The Olds was (gasp) considered the least desirable due to a "longer stroke" and other technical issues. I don't know if they know what they're talking about. But does anyone have thoughts on the merits or considerations of using a non-Olds motor?

Thanks again. I found a '70 Buick wagon with a 455/4 barrel, in great shape with very low miles. I like the car on its own merits. But also thought I might swap motors someday: My 350 into the wagon, 455 into my '72 Cutlass.

as for desirability, I would rank buick the last and pontiac first - simply because the aftermarket was kinder to pontiac 455's
unless you found a gs stage car, the 455 is designed to never see much above 3500 rpm and pull around a 5500lb car....for hp numbers from buick, I liked the 430 better....

great demo derby car...but if the body is mostly rust free, a great restore project....
