I don't think it would be very close if he's actually making 580 RWHP in that 3,000 lb car vs. the Z06. I think he said it weighed around 3,000 - maybe it's 3,300. He may not actually make that kind of power on the street though, who knows, he seems to have some problems with it. Taking 300 or 600 lbs off of the 600 RWHP KB Cobra's you're even with would put them out ahead a few.

That night he ran Deon he obviously wasn't making very good power, and the fact that they were both racing uphill doesn't give one or the other an advantage since the force of gravity is still affecting both of them equally.
