The first motor put into this project was a stock 3.0L, then a 4.0L Ford motor replaced that, and now the truck is cradling a Chevy LS-1. A Ford being pushed by a Chevy? As Kyle mentioned, he runs what works. The Chevy motor is putting out just over 400 horsepower and 420 ft-lb of torque. Attached to the engine is a UMP Air Filter System, custom headers built by Warner's Muffler, Magnaflow exhaust and a PWR radiator.
