The forefather, the Willys Jeep Truck, was only powered by a 2.2-liter flathead four-cylinder engine, capable of producing a measly output of 72 horsepower (54 kilowatts).
That's why when Billy Holton restored and modified a Willys Jeep pickup, it had to shoehorn a huge V8 engine inside – but that isn't the only thing that's amazing with this build, featured on the episode of Barcroft Cars embedded atop this page.Beyond the aesthetics and the bulk of upgrades on the truck, Holton believes that its engine is its heart and soul.
