You're gonna make good torque regardless, and you certainly have the top end hardware to make some power. Now I just need to guess what rpm the curve starts to roll over? While that combo is crying out for a 1 3/4-1 7/8 step header, I'm going to knock a few hundred rpm's of the top.....So my hp revision is 575hp @ 6100.
Thanks for the opportunity to guess Vern :thumbrig:. It's always humbling when I find out how far off I really was...lol.
