what size motor 8 or 6 dump the tranny auto sucks anyway dont know much about stangs but good headers hookers is what I would use and nice cam gt40 heads short throw shifter 9 in rear end or you can go all out and get a procharger or vortec blowers or a really nice turbo kit it just depends on how much you have and what you want to do with the car daily driver or track car have fun
