I completely agree that the V6's, whether 5 speeds or automatics are beatable. Though, the new 5 speed V6 Stangs really arent too shabby. I had a race with a 2001 with pulleys, intake, headers and a full exhaust. He put up a better fight than my friends old 5 speed 97 GT. As far as Trans-ams and Z28's, forget about it. You wont keep up, period. Especially after 70-80mph. In the right hands, high 12's are capable with stock SS's. Theyre very underrated from the factory, and mean as all hell. Turbo? Yeah. Go for it then :D
