No.. I was talking about the CTS-V.. but posted it under your reply.
A CTS-V Pully Swap alone would boost the engine to about 630HP. The LS3 in the Vette with a simple tune and a CAI has yielded me about 418HP at the wheels (approx 480 at the Fly) in my Vette. It was done a Mustang Dyno and the tech that did it told me that the thing was normally conservative by about 5%. A Cam swap would push well past the Z06's 505.
GM is notorious for doing this... essentially putting out cars with lower power rating.. then coming out later with higher numbers for the same car by some grace of GOD and a supposed recalibration of the ECM.
