non ford question..A buddy of mine is restoring a 78 chev 1/2 ton, he collects this and that and has a 1971 oldsmobile 88 with a 455, He wants to put in the 455 in the chev ( Chev has a turbo 400 ) I'm of the opion a 455 Pontiac engine is stronger and I'm not asll that techincal with GM, all I know is Buick, Oldsmobile and Pontiac made 455 cubic inch engines that are not all the same....

 

I did this almost this exact same thing. I put a pontiac 400 into a 84 Chevy. I had to buy a adapter plate to bolt the tranny up to the pontiac motor, but it worked flawlessly. I had to put new motor mounts and change some misc wiring, but it ran very strong. Hope this helps.

 

My first car was a 1969 Oldsmobile Delta 88 with the 455 Rocket motor. Let me tell you what -- that "fother mucker" moved out for a big car! Your buddy will have one potent little vehicle if he moves ahead with his plan!

 

455's have gobs of torque

should be a real sleeper

...zap!

 

Of the 455's, the Olds was the best, followed by Pontiac, and then Buick, but all three were kick *** engines. The Olds had the longest stroke.

As mentioned, this swap will require an adapter plate for the tranny, and new mounts. Otherwise, it shouldn't be hard at all.

 

I had a 455 1970 Olds 88 and a 455 1974 Olds 98. Both were very strong engines.
