motor swap

I'm looking into getting a 5th gen/1985 Chevy Nova from my cousin/uncle. I want to do a motor swap and make it a manual but are there any motor swaps that're semi easy?

Alright guys so here is the deal. I have a 79 impala that has been in the family since new. It was my first car and I love it. The thing is it finally had a heart attack. Came from the factory with the 305 2 barrel and at 220xxx miles its just worn out. Now, I have acquired a 5.3 vortec engine...
