What type of gains should i expect from my 383 stroker kit. I mean typically what type of numbers do these usually put down. I have only a couple of toher mods and they are in sig. Let me know what i should look for. extra 50? maybe 100? Also tpyically what type of times and traps speeds do they ususally put down with the 383. Thanks Cory

 

Gonna need more info about what cam and what heads before any reasonable guess can be made.

 

Roughly 1-2%hp, and 9-10% more TQ then a 350 given the same setup. The potential is all in the heads, and you've got to go big to feed a bigger motor.

 

stock heads and cam, do i need to put heads on, I dotn wanna spend 1000 bucks on em. Or do i have to? Any other good prices on a set of heads or will porting mine out work as well. Thanks Cory

 

1G for a set of LT1 heads will get you junk. Porting your stock heads is the cheapest way to go but that will cost more then $1000 for a good stage three. A good set of after market CNCed heads to work with a 383 would be beteen 2-3 Gs.
