You still might see 350 at the wheel unlocked. What will be a bigger number is that torque, especially with the stock ls1 cam, which came from the vortech 6.0L truck engine. My original stock ls1 with a 3500 stall, stock exhaust made 298 rwhp, 348 rwtq unlocked. My guess is you'll gain 50-70 at the tire with heads, exhaust, and intake over mine.

Well, as for that, my '01 has a 383 with LS6 heads, American Racing 1-3/4" LTs, 3" y-pipe, 3" cutout with an awesome Comp Cams 230/236 114+4. Love the sound and idle. With the stock displacement, you might do a 224/230 114. I drive mine everyday and wouldn't recommend anything crazier than a 114 LSA. That's coming from Geoff at Next Level Performance, who knows his stuff. I hit the dyno tomorrow morning at 8:30 am.

Absolutely yes! What I'm really impressed with is the way the cam changed the power delivery. It isn't as instant as a higher torque cam, but it carries that power all the way to the top, 6500 rpm. I thought wheelspin was going to be an issue, but with the 8,000 mile treadwear on the nittos, it isn't. Definitely has me planning on cnc'd heads and a FAST 102. Ty, the mechanic at Next Level was telling me " You're probably one of those people who don't stop adding power!". He's right. I got a taste, and I want more. With fresh tires, drag struts, and 450-470 at the wheel, I might be pretty satisfied. And, it definitely pulls from a new Camaro SS. In the graph, RED is before cam + exhaust + inj.
