Under the hood, the TJ's engine bay is simple and uncluttered. Resting between the tube rails is a 502ci RamJet V-8 crate motor that's been left completely untouched, save for the addition of Sanderson headers, Spin Tech mufflers, and 3-inch dual exhaust; all belts, pulleys, electrics, and ancillaries are stock-from-the-box GM Performance parts, not counting the Optima Red Top and dual electric fans. The engine cranks out an estimated 502 hp and 500 lb-ft at the Centerforce flywheel, which in turn powers the SM465 transmission and triple-sticked NP203/205 double transfer boxes.
