Any small block V8 with the holes in the front of the block drilled and tapped for the mount brackets will bolt in. If you use a 350 from the 1980's or newer you'll probably have to install a small diameter harmonic balancer- - - -the 8 inch balancer will probably interfere with the front mount brackets. I've seen a few installations with those brackets notched out for a big balancer, but it looks kind of Mickey Mouse, and the smaller balancer works OK on the 350.
