A vehicle capable of low-6’s is going to need a lot of power. Karl turned to Steve Morris Engines (SME) for a twin-turbo 672 ci big-block Chevy V8 capable of running 93 octane fuel for the street or C16 race fuel for the track.

The turbo system uses two Bullseye Power Pro Mod 98 mm turbochargers with two Turbosmart 60 mm wastegates and blow-off valves. The fuel system uses 16 Billet Atomiser 235 lb/h injectors and a Waterman mechanical fuel pump. The engine made 2992 horsepower and 2377 lb-ft of torque on 93 octane fuel. It made 4002 horsepower and 2977 lb-ft of torque on C16 race fuel.

The V8 is mated to a Bruno converter driver on an air-shifted Lenco CS2 three-speed transmission with a Browell Pro Mod bellhousing and Pro Torque EV-1 converter. Power is sent to the rear wheels through a Mark Williams modular 9.5-inch floating rear end with 3.25 gears and 40-spline axles.
