caddy to truck engine swap

My question is simply this:
Do older cadillac engines(ie, 1979 425 inch engine)share the same transmission bolt up pattern as chevy 350,s from the same era?
Will my SM465 standard shift truck tranny(L,1,2,3) bolt up to the 425? How about a flywheel for the 425? Does such a flywheel exist that will work?
