Shipped complete from Chrysler's Marine and Industrial Division, the 426 Hemi motors had been built offline by skilled technicians. Conservatively rated at 425 hp, the powerplants were swiftly factored to 500 by the NHRA. The V-8s were all-iron (4.250-inch bore, 3.750-inch stroke) assemblies with mild Street Hemi solid-tappet cams, 12.5:1 Dykes-ring pistons, and cross-ram eight-barrel intakes. Hurst issued Hooker headers and either TorqueFlite automatic or slick-shifted four-speed manuals, plus the appropriate wet or dry coupling in between. As with all of Chrysler's regular-production Hemicars, auto trans models received 4.89, 831/44-inch rearends, while manuals got comparably geared Dana 60s. And to match the bigger wheel-lug pattern on their new B-Body back axles, front rotors designed for A-Body Trans Am service were fitted. This Car has been upgraded in every possible aspect including the 600 horsepower. A lighter Control Freak Suspension seamless DOM steel tubing cradle replaces the Dart's welded steel K-member. It carries the steering rack and has a pair of pads that accept motor mounts and insulators from Schumacher. This avoids the vibration-prone elephant ears solid-mount approach typically found in Hemi Dart clones, but it raises cradle loading. The brakes are from Stainless Steel Brakes.
