1973-1974 Chevrolet C10 - Gen III Hemi Swap

The 3rd Generation C10 was a clean-sheet redesign that lasted GM 15 years. Like its predecessor, the Square-Body C10 featured optional small and big-block V8s that make this one of the most versatile bases for your build.

If you want to throw a curveball at any unsuspecting onlookers, our Gen III Hemi swap systems are sure to grab some attention.
