The LS3 is in fact,
extremely flexible!!! Check this out:

Our best baseline pull found the '08 to be good for 379.60 hp and 365.52 lb-ft of torque at the rear wheels. Using a conservative 15 percent correction factor to compensate for driveline losses puts the LS3's flywheel numbers at 446.58/430.02, easily eclipsing the factory ratings of 436/424.

Seems GM may be up to their old games, again?

With the 400 rwhp mark in sight, AntiVenom's Greg Lovell decided to do a little high-performance experimentation. First, he removed the stock intake tract in an attempt to roughly simulate the effects of an aftermarket induction system. Output jumped to 392.60/377.70, or 461.88/444.35 at the crank. His second tweak involved removing the LS3's accessory belt to approximate the benefits of an electric water pump. The results were stunning: 404.03/391.4 at the wheels, or 475.32/460.47 at the flywheel! Add a set of long-tube headers and a more aggressive PCM tune, and LS7-quality output seems well within reach.
