Answer 1

Any of the Gen 1 Chevrolet small block V8s will bolt in with few modifications.  I have seen these as large as 427 cubic inches in the mid 500 horse power range.  I think you can find them even larger, but not much larger in the small block Chevy.

I have seen big blocks (502) in these.  But the people who did the work had to get creative.
