Holley offers a Gen 3 Hemi V8 swap kit for 1973-1986 Chevy C10 2WD trucks. The base kit costs $651.62 and includes clamshell engine mounts, polyurethane engine mount insert, engine mount brackets, transmission crossmember, and polyurethane transmission mount. Holley designed the engine position to keep from modifying the firewall or brake booster. Swapping a supercharged Hellcat V8 will require a smaller brake booster. The transmission mount uses modular brackets which allows for a range of transmissions such as 8HP70/8HP90 eight-speed, 9HP75 nine-speed, NAG1 five-speed, A727 four-speed, 545RFE five-speed, and 46RH/46RE four-speed automatic transmissions or TR6060 six-speed and TKX five-speed manual transmissions. Some transmission choices will need an adapter.
