I'm thinking 640-660 HP at 6600, but not sure where the torque would fall... maybe 560-580 around 5400?

I hope he dyno tests it and post the results EDITED OOPS, my bad I was looking at the exhaust side thinking it was the intake side , Brad is probally a lot closer than I am on this one Last edited by Cab_Burge; 08/08/11 10:07 PM.

I was thinking of going bigger on the cam, but the guy who specd it out made sense on why he recommended that one. No dyno time for this one since I spent all my money on the parts.
