433rwhp with stock parts!
Only part not stock was the cam. Lingenfelter GT1-1. stock tb, stock airbrigde, ls6 heads, ls6 intake, (both ported) new stock lifters, long tube headers (american racing) oh, I already had a vararam, but it was not a factor on the dyno. The dyno was a Mustang Dyno. No expensive heads or Fast intake. I am amazed at the outcome, with stock parts. I have a 03 ls1 vert.
Ever gonna take it to the track?

Stock rocker arms are not a problem. Don't forget that the new LS7 Z06 engine uses the same type of rocker arm. He does have hardened and .083" thick push rods to resist any flexing under the new heavy springs. Otherwise, the heads are GM 243 LS6 castings with larger valves and the appropriate springs for the GT1-1. For all street applications GM rocker arms are adquate, in some cases where the car is going to be on the track, I suggest a shaft mount solution such as the Comp, Crane or Yella Terra rockers. Jessels are great but usually a bit high on pricing for most customers.

10-15% conservative!
It gets addicting. I just started dragging my car and can never wait to go back!
Im anxious to see if your car can back up its numbers at the track. Any other mods to your car? Like a clutch to handle the new power or a hardned output shaft?Haha, opposite sides of the country. Glad to see your loving it so much.

Sorry guys, you are right. I have stock heads and intake but the intake is not really stock it is ported. The same with the heads, bigger valves, comp springs. My point was i guess is that i did not have to buy expensive heads and intake, or rockers. you guys are right they are not stock parts. I stand corrected, thanks for correcting me, i just got so excited i guess.

Understood as most H/C packages are set up that way. Buth the statement that the only part not stock is the cam is a little misleading since the springs and pushrods aren't. I guess its open to debate but I wouldnt consider ported heads a "stock part". Yes they are stock ls6 castings but nowhere near what came off the factory line. I assumed it came with the appropriate valvetrain like it did but just wanted to clear the air. No doubt, good numbers

I am pretty happy, there was a C6 in the shop that had a Fast intake, ported larger tb,he installed a new cam (not sure the specs) and had a tune, and of course 383 cubic inches. He made 12rwhp LESS than my LS1 (which is basically a LS6 now)!
