The Camaro is roughly 200 lbs heavier, however, the Mustang has very aggressive closer ratio gearing (a little aggressive even for that type of power curve, IMO).

While the MT82 does have aggressive gearing, I have owned a 14 SS 3.45 TR6060 , a 13 GT MT82 with 3.73 and now a 14GT Mt82 with 3.31. The 3.31 ratio with the MT82 isn't much more aggressive than the 3.45 in the SS. I feel the 3.73 in the Mustang is too much.(I Pull on the top end of my friends car with the same mods and tuner except he has the 3.73) The Ls3 had a flat power band where as in the Mustang once past 4k rpms , has the feel of a boosted car.
