What ever the horsepower was with the fuel injection and computer on the 2010 Vette ,it is no longer the same with no computer, and fuel injection . You would need to dyno it and tune the carb and ignition to maximize power . If you can get the computer, intake, fuel injection and ignition with harness from a 2010 Vette you would have a better running car that makes as much power or more with better fuel mileage . Just something to bear in mind .
