Just got an inheritance, looking to spend it wisely
what do you guys think, most of it is in order how i want to do it. looking for street/strip trying to get into low 12's. What do you think the priority mods should be. obviously doing bolt-ons first. Trying to get most bang for buck right now, just want to make it more aggressive for street. dont want to do any BIG jobs until it is stored for next winter. how much hp/torque do you think i will gain? advice on heads/cam?
