Porting and polishing

Just a question becuase im bored and havent been able to got the track for a like 2 month becuz of school

I have a 86 carlo weight 2500lb (im a poor boy, light cars go faster and its free) anyway i have a turbo 350 going to a 4.56 rear end...the motor is a 350 chevy, headers, performer rpm intake, .500 lift solid cam, flat top pistons, late model vortec heads,750 holly...anyway my best time is a 12.69 at 107mph.....i just had a pocket porting job done to match the gaskets.....any guess what i will run when i make it back to the track....i have 10.5 slick so there is no spinning on take off

Maybe a few tenths off of your previous....Hard tellin

depends on the guy who did the job also, how well he knew what he was doing
