Then that means 99 Cobras must run low 15's. I raced the guy, and have the time slip stuffed somewhere; that's what he was racing all day, in decent track conditions no less. By your theory, that's how it is. If you argue this, then you are proving you are wrong about the GTO, and we can't have that, now can we???
Regardless, GTO's aren't meant to be drag strip kings anyway; they are a nice GT car, good handling, with power to go along with it. If you think your Moostang is as nice as a GTO, you are dillusional.
