I would fully agree with this although 12.6 seems a bit optimistic. The Camaro and TransAm where severly under-rated from factory. It's actually accepted that these cars came with 350hp or more at the crank with the factory. As quoted I've seen stock LS1's put down 310-320hp AT THE WHEELS. Most I've seen at the track run 13.3-13.5 in stockish form (at this age of car tires and wheels are changed on most of them). In my experience the LS1 is quite capable of hanging with if not beating a Z, but it will come down to the driver and track. The better the track prep and better the driver the better the LS1 will do. From a roll I would say it's even to about 100mph and after that the Z starts to walk away slowly; I won't say how I know this though. Also the LS1 I had most experience with was an automatic; I'm sure a 6-speed would do better.
