My friend has a 1995 5.0 mustang. It has longtubes with flows and dumps. cold air intake, 3.73 gears and a bunch of aftermarket supension parts. I have driven it before and its pretty quick, but the G8 just pulls hard on it all over the place. We probably only got up to about 70mph cause of traffic but it made me feel good. I was really suprised I even got him from a dig. He is looking for a good deal on heads cam intake, I told him to bring all he can find.
