i've got a stock 383 from 1971 and as far as i know 70 was the last year for 11.5:1 compression in the 383s. so i believe this engine is pretty low on power. it is an orginal 4bbl if that matters. i'm trying to do a low budget boost on power and want to keep it stock looking. i plan on porting the heads and then lapping in the valves, i'll check the guides and make a decision as to whether to install new or not. don't plan on adding new seats. i haven't checked the pn of the heads but i'm pretty sure they are open chamber and i don't want to spend a ton of money on them. btw the engine is original to my 71 convertible so i don't want to mess with it too much but i'd like some more power. i am planning on changing intakes and i'm keeping the exhaust manifolds and stock exhaust.

so new timing chain, new springs and new cam are definitely on the list. i will redo the bottom end at a later date so no new pistons right now. any other options?
