Even full bolton C5Z will barely pull those numbers and they typically dyno a little more with the same mods as a V.

If the numbers are right that is a record for a basically stock car. Stock dyno#'s are around 330-335rwhp. A tune and K&n would put you around 345-350 at most. Muffler delete does not add any power. They somehow found 35 additional HP. You might have gained a FEW with the LS7 clutch setup but def not 35. Nice numbers either way so dont take this the wrong way. Just seeing as many dyno's as I have from LS based cars, they seem extremely high for the mods. There are a few cammed V's that struggled to hit 395rwhp with headers etc....

335rw stock? Is that a joke? I did 358/348 with a intake, untuned on a dyno jet at my local UTI school last July when I first got the car, corrected #'s of course.

With that said said, dyno dynamics dynos have a tendency to read lower, like a mustang dyno because they're a loaded dyno. He has the correction factor setup to read like a dyno jet, because those are the common dyno's people use. Regardless, he can compare stock C5Z runs to his and it'd all be relative because it was done on the same dyno.

Either way, the car is strong. Congrats!!
