However, it is still 500 hp vs 425 hp (supercharged Stang vs Challenger). DCX must either supercharge the 6.1 or give us the 6.4 to stay ahead of the pack.

after hearing the audio clip of the 6.4L in the S/S concept there is little doubt in my mind that will be one scary a$$ motor even in detuned state. The only place I've heard anything that sounds like that is on a race track.
