I have a GMPP L31 350 which has vortex heads. I scored it for $600 from a wealthy dude who upgraded to a LS. It was the only thing I could afford at the time. I installed a mild cam and Fitech fuel injection. I am considering purchasing a short block 383 from Skip White Performance since it will work with my heads, cam & FiTech and take me from 300 to about 400hp. The drawback to a higher HP 383 is that it would require a high stall torque converter which isn’t very street friendly, unless you have a manual transmission. If I were to do it all over I would get a low mileage LS with a 4L60 before I spent $4500+ on a new GMPP crate engine. SBCs are great but if you want a street/strip car you simply cannot beat a hopped up LS.
