I've read about a few and they were dyno'd 620-642 rwhp. And C7 Z06s are the 560-580 rwhp range.

I cant see why any car company would max out a engine from factory.

GM didn't tell anyone until the car was in the hands of its owners (and thought it was heat soak) but they have a very conservative tune on the car. It pulls timing and reduces power. Pushing the car full throttle will cause it to interfere. Vengeance Racing noted that when they got their car, dyno'd it and looked at the logs.
GM also said that after 500 miles or 1000, I don't remember, the car will be "unlocked" and the full potential will be unleashed. Though that doesn't seem to hold true right now.
