Also, ref our previous messages, I mistakenly thought GM was claiming 495 RWHP, but they are saying it's at the crank I guess. So that makes the difference even more because the dyno testing shows 561 RWHP so they figure 660 at the crank. But that is using a 15% drivetrain loss. GM claims they've got the loss down to, I think, about 8%. So reduce the number from 660 HP to 610 HP.
Still... ;D

Since the early 70s, I believe all claimed HP is SAE net at the crank with full exhaust and all accessories. (previous SAE gross could have open exhaust and no belt driven stuff).
