The 2004 Ford F-150 SVT Lightning came from the factory with a supercharged 5.4 L Triton V8 producing 380 hp (283 kW) and 450 ft-lb (610 Nm) of torque. A listing from Cars&Bids states that this F-150 SVT Lightning is now powered by a supercharged 5.4 L Modular V8 from a 2009 Shelby GT500. The listing states the motor features a 2.3 L Trinity TVS supercharger, Accufab Racing single-blade throttle body, 72 lb fuel injectors, upgraded MAF sensor, and 2-inch Kooks stainless steel headers. The result is 623 hp (464 kW) and 591 lb-ft (801 Nm) of torque. The truck came from the factory with a 4R100 four-speed automatic transmission and Eaton Detroit Locker differential. No word on if those were retained. The only other detail on the drivetrain is the truck has a four-speed automatic transmission.
