Power is based on a Chevrolet Performance LS 5.3L (327 ci) with iron block and aluminum heads. To this a FAST LSX RT 102mm intake system is used with the FAST computer. Cooling is handled by a U.S. Radiator copper and brass system. The A/C pump is moved from its lower position to a higher spot with a Kwik Performance relocator kit. FAST fuel rails and injectors are all part of the fuel delivery system along with Aeromotive fuel pump and pick up.
