I would look for a large FE engine such as a 390 or 428.


A 428 is going to be a hard one to find, restoration people have grabbed everyone they can find running or not, 390 is a little easier but it will take a lot of work to get it to 400HP on pump gas. If you got the bucks try summit racing for a crate engine, a C6 transmission with a trick kit would be a nice match.
