Of Course it is It been Detuned- for "safety" otherwise why would it be the engine the new 6.4/392 is base from? It has more compression than the 6.1 and the 5.7 HEMI is the newest version of the engine in the 2009-10 Dodge Challenger/Charger/300/Jeep. Not saying that it has more ponies than our SRT siblings but it has the potential(with modifications) to be a quite a serious contender.
