As you can see 422hp rating is severely underated. Since this time around the vette and Camaro have an IRS, the drivetrain loss should be near the same. As mentioned before the LS3 vette average over 390 to the rear wheels thru a M6. Lets say that the camaro and the vette both have a drivetrain loss of 20%.
The vette's LS3 is rated at 436hp. But musters 32hp to the wheels.
I strongly believe that the differences (pulley, alternator mounting, and intake) will effect the Camaro at the very least. If it does effect it at all, and considering the corvette's LS3 response to bolt-ons; it become a moot point in the end when comparing vehicle mod for mod on the dyno.
I think the Camaro will pull at least 390rwhp on dyno stock.
