FWIW, here's a graph from the '05 GTO.

About the same peak torque and 5 less peak HP than a decent LS6. The top end rolls off a little beyond 6000 whereas the LS6 is flat to the redline, but the LS2 has a little fatter bottom end and midrange, which will be real useable in normal driving.

Looks like an honest rating, and the RWHP and torque curves are exactly what I expected compared to the LS6. Depending on exhaust system efficiency, C6 LS2 could come in a little more or even a little less.

The 5-6% torque advantage the LS-2 enjoys in the midrange is half offset by the 3% taller wheel/tire combo of the C6. So the net advantage is much narrower: about 3%.

Also, I have never seen such an irregular torque curve as the LS-6 engine depicts. Actual dynos from our members show a much smoother curve, and much fatter in the middle. If I can find my dyno sheet, I will post it...looks nothing like this.

Maybe they used a Monday LS-6.

Also, I find GM's torque graphing a bit silly. Why not use full scale and show it like it is. How ricey of them.
