Somebody can correct me if I'm wrong here, but from what I understand, the 6.1L hemi already has VVT and is one of the 1st ever to offer it in a push-rod engine. I understand that's how they push so much power from these engines and why they rev so nicely. It only makes sense that it would eventually trickle down to the 5.7L hemi. I've heard rumors of the 6.4L hemi having 525+ hp, but that figure seems kinda high unless they make some major changes to the way the engine breaths or offer some sort of forced induction. My guess would be more like 450-460 hp NA at the top end. The 7.0L Z06 is only pushing 505 hp and that engine breaths waaayyy better than ours do. Even the Viper's 8.3L engine is currently pushing just a little over 500 hp.
