I plan for this car to be a street strip car, something very street able but something I won't be ashamed of at the track.
70% street , 30% track
The suspension is completely redone along with all new steering components.
The real question starts now, what would be the best head and cam combo because what I have now is no where near matching each other or my stall. I want heads that'll fit with my intake and be in its powerband range and also fit my headers and I need a cam that will match with the heads and the stall I have.
Right now the heads and cam don't match, the heads are over ported and leaving no velocity, the cam is a pbm can that I know nothing about othe than .498 lift, and the valves and rocker arms are stock.
A buddy of mine has a 302 with a 100k+ mile stock bottom end with a Ford Racing roller cam (E40?.. its apparently a popular roller cam for a sbf) and a set of GT40 heads with a weiand stealth intake and carb and runs really good. Its in an 80s foxbody with a T5. Last weekend he was running mid 14s at 97 mph with no tuning on the carb or dist with a bad bog off of the line (next weekends project).
Whats your budget look like? If its not a lot go pull a set of gt40 heads off of an exploder from the yard and have them rebuilt and throw in a roller cam to match the heads and intentions of the car.
Otherwise there are plenty of aftermarket aluminum heads available for a sbf.
