The stock TBI 454ci V-8 engine runs great and produces plenty of horsepower and torque, so Lorenzo left it mostly alone for the time being. He did install a custom exhaust system with Magnaflow straight-through muffler to help the engine breathe a bit better. Fuel is stored and supplied by the stock 44-gallon fuel tank. Flanking the engine is the stock 4L80E automatic transmission.
