Very nice combo, Im using many of the same parts on my build. I have everything here sitting in my garage going on over the winter.
WCCH LS7 stage 2 heads that were hand finished by Brian Tooley Racing
LS7 Rockers with Comp Cams trunion upgrade kit
Brian Tooley Racing 246/254 and .652"/.630" 111+2
Bone stock shortblock
American Racing 1 7/8" longtubes with Hi-Flow cats
LG4 3" Catback exhaust
Fast 102 Intake ported and port matched by Brian Tooley Racing
Nick Williams 102 Throttle Body

ATI 10% underdriven crank Pulley
Im really hoping to eclipse the 600+ rwhp mark with this combo.

That's awesome Jason. That's 15 HP more than with the stage 3 cam and should be more driveable. Win win for the Kavorka!
