The tightly-packed engine bay houses a GM Ram Jet 502ci V-8 that puts out 502 horsepower and 565 lb-ft of torque. Some of the engine’s features include an MSD Pro-Billet distributor, Sanderson headers, Dynomax mufflers, and a 3-inch-diameter dual exhaust. A custom 10-gallon fuel cell feeds the engine and an Optima YellowTop battery provides cranking amperage. Keeping the ’plant cool is a custom Forx radiator with two 14-inch-diameter electric fans. Bolted to the engine is a PTC TH400 three-speed automatic transmission with a custom valvebody. It’s cooled by an AFCO extruded cooler and shifted by an Art Carr shifter. An Advance Adapters Atlas 4.3:1 ratio two-speed transfer case sends power to the custom Grand Forks Welding-fabbed driveshafts. The front shaft is made from 2.5-inch-diameter, 0.750-inch-wall material and the rear ’shaft is made from 3-inch-diameter, 0.750-wall material. Both driveshafts use 1410 U-joints.
