Powering the Jimmy is a GM Performance 350ci V-8 crate engine that Decker says makes approximately 330 horsepower. This is a vast improvement over the rig’s factory 350ci engine that was reported to have 210 horsepower when new. Decker’s engine has throttle-body injection, Doug Thorley long-tube headers, Magnaflow muffler, 3-inch-diameter exhaust, and high-flow catalytic converter. The engine is cooled by the stock radiator and the stock mechanical fan. Electrical needs are met by a 160-amp alternator and a pair of PAC isolator-equipped Optima batteries located above the passenger side foot well. In this image you can also see the heavy rubber material that serves as inner fenderwells to keep crud off the engine.
