My stang is stock and of course i just cant live with that. I know the gains that will be made through power adders but I'm worried about engine problems. My car, though she runs good is no spring chicken, she sits with 118,XXX on her now. I'm worried that going with a power adder at this mileage will only increase the chances that something will break. I believe my only option is a (Cobra) Engine swap. This way have a good place to build from. What do you think? So before i even go and get a CAI or TB I'm gonna hold for that old 4v. Anybody know a good place for engines? What price range are they?
