Not too surprising. The GTO has the new 6.0L LS2, which makes a lot more horepower than LS1 that was in the Trans Am. This helps offset the extra weight of the GTO. All this assumes both cars are stock. If you are going to street race, why stay stock?AF said:Those are 2 very fast cars !!!
I am really impressed with that GTO ... the fact that it is actually pulling from a Trans Am is really impressive.
