egnine rebuild questions?? whick one

I have a 72c20 cheyenne super. it has a 90's gm goodwrench crate engine that is smoking. My dad has his 350 engine from his 70gmc that was replaced by the dealer I think in 1971. Should I fix/rebuild the newer motor or the older block? Also if I were to rebuild the older block will I have less power if i just make it stock w/ rv cam? Can I use the newer heads on the old block? What are the advantages to each?
