Is a small block hei the same as a big block hei? If there's a difference, what is it? Thanks for any help.

The advance rate will probably not be quite right, but they differ from engine to engine year to year...ect.
As far as pulling out and slapping in, yes, it will work small block to big block. It is actually the only thing that will swap over. (well...the carb will too)
