383 help and guesstimates!! I purchased a 72 Chevelle from a friend that has a 383 stroker in it. Im looking for some hp estimates and maybe which way I should take it. I dont know too much about specs and all, but here are the basics
Its a 383 stroker, it heads are the Edelbrock Performer Rpm w/angled plugs. If you need some specific specs to help with a guess, I can provide.
It also has the performer RPM cam and @.050 its like a 234/244 w/a 112lobe.
It also has a Holley 670 carb.
Im just looking to see if you can give me a guess on what you think the power is currently untuned, and what you think I can get out of it by tuning.
Im also wondering what would be the ideal sized carb for the best power gains, the previous owner was going to go with a Holley 750 dual pump. Any help is appreciated!!

well judging from the carb size, its probably got a relatively low compression ratio in terms of performance engines, the cam seems decent for a street/strip car, the heads are aluminum im assuming? im gonna guess around 300-325 horses at the flywheel, its hard to make an accurate guess with the little amount of info provided.
