I have a stock 1971 Cutlass Supreme since 1990 with 262,000 original miles. My mechanic is parting out his 1972 442 (350 2 barrel). He offered to sell me the engine (54,000 original miles), along with the turbo 350 transmission and differential for $950 (cost with installation $1500). My engine is rated 260 HP and I think his is approx. 200 HP. I would prefer more power, not less. Should I go ahead to have it done, and do I suggest that he install another cam (Comp or Crane), an Edelbrock RPM intake manifold, a valve job or head porting? I would like at least 300 HP without spending a bundle. Please help!!! Thanks.

Welcome to the site, post some pictures when you get a chance. You can use his engine for the time being and rebuild yours as you have finances and time. Heres a good read:

For the 1972 model year, those numbers were exactly the same. The 4bbl 350 motor was rated at 180 HP net with single exhaust and 200 net with duals. The 2bbl motor was 160 HP and 170 HP, respectively.

Thanks to everyone for your help and ideas, especially to Joe Padavano for the helpful charts. I will probably buy my mechanic's engine and transmission with only 54,000 original miles, since mine has 262,000 miles, and my transmission was rebuilt twice.

I merged your 2 threads to continue the original conversation. That's a really nice car. When you have your mechanic swap engines, you might ask him to reseal any leaking gaskets, inspect the freeze plugs, and check/replace the timing chain.
