A buddy of mine who has an '03 gt swears to me a 99/01 cobra is completely identical to the 03/04 mach's. I explained that the mach is the same motor(4.6L 32v) but has different cams, different intake, different compression ratio, and different rear gears. Also the mach's have 5-15 more hp and tq then the 99/01 cobras. Please help me settle this arguement, and put 20 bucks in my pocket, lol. thanks guys.
