I don't think what it is potrayed as is what is happening. There is no smoke/slippage on the Chevy side like there would be if it was in gear and pulling. Now maybe they had the brakes on to make the jeep smoke a bit then it looks like the breaks were let off at the end. I also find it hard to believe that that could actually happen given the chevy is most likely a big block V8. I could be wrong but I doubt it.
