Do a search here...you'll find hours of reading...
You'll need to get a V8 truck bell housing, V8 throttle linkage and you'll need to make sure your late 70's engine has the front motor mount bracket holes drilled and tapped...I think Chevrolet stopped drilling then in the early 70's, but I could be wrong. The Rams Horn cast iron exhaust manifolds work great. You'll need to find or make a fan shroud, the 6-cylinder one will be to short.
I think that covers the major stuff...
