That's not really saying much, because you are comparing a stock 2011 to your modded Z.
FWIW, the 4.6Ls rated at 315 hp dyno between 270-280 whp (dynojet) and put down around 330 whp with intake, exhaust (CBE and HFCs) and a tune. Drivetrain loss should be similar, so expect around 355 whp stock out of a 2011.
But yeah, I don't know why anyone would buy a 2010 knowing that the 2011 was getting that much of a power increase.
