Well.. After losing my 5.0 going out and buying a 03 350Z (touring) i relized how much i miss my stang. So i went out and got a 03 Roush StageII. Ive been reading over the newbie 4.6 Posts for hrs now. Ive got Jus a few questions... First, Gears what im really wondering is what is the top speed in 4th gear with... 3.73, 3.90, 4.10. With stock tire size. My old stang i was trapping the 1/4 at 110mph in 4th and was damn close to redline. That was 3.73's. Next question if anyone knows about Roush suspensions im curious if anyone knows a slalom mpg or skip pad G for it compared to a stock GT. Next question. Roush CAI vs others??? Should i leave it or is there better?? Next question (which i did not even research) but is it true to put headers on the car you have to drop K member?? Thats all i can think of right now...
