This is from the GM press release. Incredible!

The LS9 won't be getting its final certification until about March, but so far GM has put over 6,800 dyno hours on the new engine. They have run an engine for 100 hours continuously at wide open throttle and done both simulated and real 24-hour track cycles similar to what the GT1 C6.Rs run on the dyno and in the car. Thanks to the extensive simulation and modeling done prior to building any parts, the engines have been remarkably reliable. To date, through three years of development, they have never had a failed piston, connecting rod or crankshaft in testing. The simulations have gotten so accurate that the first prototype engine on the dynamometer ran within 3.5% of the simulation throughout the entire power and torque curve.
