Estimate RWHP Number

I just picked up a 2000 FRC with 65,000 miles on the clock. First round of mods will be cam, Texas Speed long tube headers with a catless X pipe and a LS6 intake. Cam specs are 227/234 614/612 on a 113+2. What should this combo make as far as RWHP and RWT? DynoJet dyno that is a little stingy.

As a comparison, I have a 99 coupe with 231/237 cam, vararam, LS6 intake manifold, LG headers, BB RT 66 Catback, and tuned by Speed Inc. I made 393 RWHP

Thanks for the response. Can't believe none of the other LS1 gurus haven't chimed in. I was figuring somewhere between 380rwhp and 400rwhp.

Mine made 418, with the only difference being cam choice and everything of course relies on tuning and drivability.its gonna be fun no matter what the actual numbers are.

Be prepared to buy a clutch possibly
