What should I do next?
I have a 89 GT that is stock besides a 6psi supercharger, mild cam , and im goin to get full 3" exhaust. Im trying to figure out what heads and upper an lower intake manifold I should buy. I want to keep my car drivable. Also what # injectors and size of fuel pump I should buy. I live at home with only a few bills but I dont want to spend a outrageous amount in it.
