Guys I found this one 5.0resto

With a mac o/r X pipe, mangapack catback, underdrive pulleys, and a steeda high flow intake would a 75mm be too much or would I lose any horsepower. Should I go 70mm or 75mm? what would be the difference?

go with the 75mm and go wit the throttle body and plenum deff

Just like at practically anyone who makes an intake plenum, most companies reccommend a 75MM TB for more power. This is N/A engines of course, some people with F/I say a 70MM TB is all you need. But for sure you should go with the 75MM

It's been dyno proven that 75 mm TB's make more power even on relatively stock GT's. Why not get a couple more ponies for the same price?
