1972-1974 Dodge W100 - Gen III Hemi Swap

In 1972, the W100 received a complete redesign that lasted until 1980. With it came more rounded styling cues borrowed from contemporary Mopar cars. An extended cab was optional for the first time ever on any pickup. Although you could option your truck with a wide range of small and big-block V8s, today you can drop in a Gen III Hemi with our swap systems.
