Mike

Says the Challenger guy? I know it can handle alot more. lol The 5th gens easily held any supercharger.

This is off of Tremec's website:

So anywhere between 430-650 ft lbs input torque as a reference.
The Challengers, vipers, 5th gen camaros have already proven this transmission is way more capable than 420 ft lbs.
