Cam 5.3s making over 330+hp

I have a dyno sheet around here somewhere. I posted it a while back, but I'd have to dig for that also. The torque curve was impressive for the lack of cubic inch. It only made 309 through manifolds and adding the Pacesetters with a little more tuning made the difference.

I also had a 04 JG truck (check TOTM May 07) It was also a LM7... The truck had to be a HO option from the plant before it went to JG.
I can't help your case as my JG truck NA with cam only and no tuning made 319 on the rollers with 22's on it, but I do know with just tuning and a set of factory wheels it would have easily broken your 330 mark... I never dyno'd her cam only after all the other work I put into it.
