Gotta at least think positive.

It is the intake and exhaust durations that Lingenfelter uses for their in-house LS-7 cam. I just tightened up the centerlines and put a slightly more aggressive lobe profile (XE-R) than they use.
LPE LS1, LS2 Camshafts 350-383-427 229/242 .631/.631 w 1.7 rocker 114 CL
By the way, those are pretty strong numbers given the fact that you have CATs and stock exhaust!

My dyno is very reasonable, and certainly not the highest in town. Been down that road before
If he is happy with it, thats all that matters. I have customers that come in and want to buy wheels and floor mats for their Z06s. They are happy with the hp it has stock!

Getting e-mail replies from sponsors seems to be a thing of the past. Maybe you'll get lucky.

i am building a 434 stroker, ls7 heads ( hoping they will flow similar to your guys heads), a 260-268 hydraulic cam on a 110 lsa .660 lift, running gm ti valves and morel lifters. ported ls7, and 13.5 compression ( 103 octane motor), you guys think i can eclipse the 600 rwhp barrier?

Exhaust
.200/132cfm .300/178 .400/220 .500/235 .600/243 .650/250
2) Spec'ed my own cam. XE-R lobed cam 242/248 110+4 .645"/.650", basically a TREX w/ 2 degrees more advance. HPE pushrods and PSI 1511 beehive springs.
3) Cometic .040 head gasket for LS7.
4) American Racing 1 7/8" headers w/ hi flow cats and x pipe.
5) Jeremy Formato ported intake manifold and HPE ported tb
6) Callaway Honker cold air intake
7) Tune by Chuck at HPE
SCR: 11.7:1 DCR 8.9:1
RWHP: 559 (452 stock)
RWTQ: 504 (424 stock) Dynojet
Power comes on really strong at 3000 and pulls to 6800 where it slightly dips to 7100. Exactly what I wanted. Sounds mean as hell. HPE are really good guys to deal with. Steven, Chuck and Josh thanks. I'll see if they can post the graph.

Nice #s! I find it interesting too because I've seen the LS2 6.0 with upgraded cam, headers and intake running mid 500 whp range. Don't get me wrong the new Z06 is one heck of a car but the extra price tag(20k+) doesn't justify what can be done to a base C6.(Gearing,susp. and brakes, etc) Which can be made even more of "Sleeper" if thats possible in the first place. lol 
I rest my case.
