ok, just picked up a wonderful 91 GT 5spd with 70K original miles for 2.5k so I have left over money to put into mods. What do I have to do to get a strong 12sec car? Here is what I already have in the garage. MAC Long tube headers Custom X pipe Flowmaster catback MGW Short throw shifter I have on the way: An Explorer throttle body, along with upper and lower intakes that will be sent off to TMoss for some port work. As well as some GT40 heads going to Thumper performance for some porting as well. What else do I need? I'd like to keep the rock cam cause I'm gonna go with the whole "its stock" thing so that also eliminates nitrous and a supercharger. Any other ideas? I'm looking for proven 12 sec combos, thanks.
