A ls3 corvette on corvette forum did 522 rwhp with a cam heads and cai. wasnt a big cam either something like 235 240. several people including rpm motorsports use a 230/234 cam and consistantly get 500rwhp and 460trq.

Do you consider a Procharger a bolt-on?

A bolt-on only LS3, about 430-450 hp. Cam only (w/ bolt-ons) about 450-500 hp. And a H/C/I setup, about 480-520'ish....w/ FI, 550-600+.

I'm running a cam-only LS3 w/ a ECS NOVI system. Without the blower, the setup puts out about 460 hp. The blower pumps it up to 570 rwhp on a safe tune w/out meth. If I added meth, 650-700 rwhp would be the norm. But it's already hard enough in keeping the rear tires under the car as is. Only reason I'd add meth is to lower IAT's during the summer.

Good luck. Hope this helped.

Yea, LG has a dyno video of a bolt-on ls3 with the g6x3 doing 500.12rwhp I believe, with some better heads although the stockers are pretty good anyways, you could see about another 25rwhp.

Agree completely. Everything I've read about LS3 builds and L92 head 6.0L builds ( and I've read a LOT ) fall right into those numbers. There are the odd exception to those numbers but I'd put that down as either freakish luck, dyno calibrations off, or bull shit factor.

Just a LS2 here. Bone stock shortblock, right down to the rod bolts.

800+whp with heads, cam, and .063 pill
