There is plenty of room for it to fit! I am sure someone has done the conversion before!

WELCOME!

Welcome aboard.

It would probably make the swap easier if you put in a pontiac 400. That way you could keep the wiring, engine mounts and transmission. 400's have quite an aftermarket following too, and if you're REAL lucky, you could find a 455 pontiac.
