Beta Chevronet Vette StingRay 1.0

For the final production year of the Vette, Chevronet released a special edition trim called the StingRay. This model had an uprated form of the Grand Sport's RT-1, dubbed the RT-4, and is only available with the 6 speed manual gearbox. This engine increased output from 305 horsepower to 335 horsepower, and yielded 10lbft of extra torque, although at nearly 1000 rpm higher.
