in my not so educated opinion, I would attribute what you felt in th cobra to the how much air the 4v heads will flow and the shorter runners(compred to a 2v intake) on the 4v intake. I am sure the cam profile has alot to do it with as well. If you look at the 4vs from the Mach 1 and the Cobra, the Mach has more low end and the Cobra is stronger up top. I think it is only a cam change I think the Mach shares either one of the cams with the aviator(I am guessing exhaust, i'm sure someone can correct me if I am wrong)
