Twin-turbo 402 CI LS V-8, currently tuned to 800 HP, with twin 67mm Precision turbos, Turbosmart wastegates, aluminum heads, Edelbrock intake and Pro-Flo fuel injection. The TH400 automatic was built by Trans Extreme with Stage 3 internals, while Childress Racing fitted the rear end with a Moser housing, 35-spline axles, 3.18 gears and a Wavetrac limited-slip. Heidts front suspension, Wilwood four-wheel disc brakes and an Autofab Pro Series roll bar complete the chassis and safety hardware.
