Hey everyone. New to this forum, slightly new to Mustangs and cars in general. I completed a GT40P swap a week ago, runs awesome, a lot more power. I am getting BBK shorties to help the plugs clear a bit better, and was wondering if a 70 or 75mm TB put on at the same time would help the car breath much better and what I could expect from the two? Here's my current engine mods: CAI GT40P upper/lower GT40P heads B cam Underdrive pulleys SCT tuner New distributor, plugs, wires Thanks!
