The only reason the Camaro was quicker than the GT was the Camaros power PERIOD. The 5.0 should have no trouble putting the Mustang GT ahead on a road course. As for the GT500, don't forget it's about more than 10 HP jump, there will be 120 less pounds over the wheels to improve weight distribution and the SVT track package, it should be a total beast. Heck, if what Ford says is correct, the V6 with it's track pack is supposed to be quicker than a GT with a track pack around a road course.
