I was just reading this old MotorTrend article (Detroit Muscle), and they did dyno runs with a RT10, Cobra R and Z06 (all 2000 model years). Z06 managed 344 rwhp, so that's pretty close to the stock 385hp at the crank. Cobra R did 376 rwhp! (it has the same hp rating as the Z06). And the RT10....425 rwhp and 460 ftlbs at the wheels. Pretty impressive numbers. That's quite a bit more than the factory figures.
Here's the article:
