David Waterworth is a professional drifter competing in the British Drift Championship. In late 2014 David decided his previous race car, a Nissan S15 with a Viper V10 which he had raced with for three years, was a little too tired to keep going. So he decided to take the 8.0 L Viper V10 from the S15 and transplant it into a 2006 Chrysler 300C. It took David, with help from his family, three months to complete the project. The engine is pretty stock producing around 500 horsepower and 525 ft-lb of torque and is connected to a factory Borg-Warner T-56 six-speed transmission.
