Have you ever been to a NDRA/Nopi event? These guys run million dollar+ factory backed operations, ride out of $250k trailors and have back up race cars. This guy runs a single man operation with 1 or 2 volunteers out of his own pocketbook, actually shifts his car down the track, and his car still weighs about 600 lbs more than them.
Trust me, its just a matter of time before the NDRA changes the rules to give the GM cars more of an advantage. I'm sure they are very scared right now.
