The framerails coddle a modified Chevy TBI 305ci V-8. This engine has a Moroso high-output oil pump and deep sump as used in circle track cars. Referring to the deep sump, Hilton says, "It helps to keep oil pressure when you're tipped in bad positions." Exhaust gases are passed through Hooker headers, 2-inch-diameter exhaust pipes, and glasspack mufflers. The V-8 is cooled by a Be Cool aluminum radiator with 14-inch electric fan that activates at 190 degrees and deactivates at 170 degrees. Howell Engine Developments built the wiring harness and provided the computer to facilitate the V-8 swap. Hilton says, "The computer is made with a removable chip, so when I do engine modifications, I mail them the chip and they reprogram the chip to my new upgrades." Other underhood mods include a pair of Optima RedTop batteries, a 100-amp alternator, and an ARB air compressor. There's also a custom airblock to distribute the compressed air.
