One of the duels of the day at the last Fast or Nothing 1/2 mile race involved this pair of Gen 6 Chevrolet Camaro ZL1's.The red one having the Neoh2ning Stage 1 put down 650 whp on the dyno and despite the fact that it has a traditional 6-speed manual gearbox, the stock 10-speed auto had a hard time keeping up with it.
