Are all the bolt on parts really worth it?
I just bought another Mustang and have decided to just lightly modify the motor. It is a 1988 GT and it already has longtube headers, 3.73's, and a mild cam. All I planned to do is port and strenthen the stock heads and put all the bolt ons like TB, MAS, Underdrives and the such. Do yall think that the bolt ons will really make that much of a difference? Also what kind of gains will I get out of the head porting?
