My Dart vs C5 Corvette Predictions???

Well at my work my fellow employees have some nice cars and were all gonna race the cars im up against are: 96 Chevy Camaro Z28:CAI,Superchips,Exhaust, 96 Mustang:stock with 3.73's and a 02 C5 Corvette with MSD wires, and exhaust

I know i can take the Mustang and the Camaro and im almost sure i can get the vette on the fact that it shares the same motor as the 02 Camaro (LS1)and its automatic and basically stock but just for the hell of it figured i would ask if i should worry
