[rboogie23]

Wats the biggest motor I can go with in a 1980 cutlass supreme without to much mod

A small block or big block will both fit just fine in the engine bay. Only major probs some run into with a big block is issues with exhaust header fitment.

How would I fix that issue with the headers

I I MADE A EGIN SWAP TO MY 1980 CUTLASS IF U HAVE ANY QUESTIONS JUST ASK ME

 

[ZZ4CutlaSS]

Olds 455, Buick 455, Pontiac 455 so on so forth! and if you have any questions I have done both swaps. Can be done very easy if you can find a good running engine.

What big block u think will be good for my cutlass

Both of our 80 Cutlasses have 455 Olds in them. Easy swap. I also swapped a Pontiac 350 in my Lemans g-body.

I have a 78 with a 455. Fits perfect just use small block motor mounts. Check out my build thread viewtopic.php?f=10&t=33462
