Sold alongside its Valiant sibling, the Duster added a two-door fastback compact car to Plymouth's lineup through the end of the muscle car era. Despite its small size, the Duster could be optioned with 318, 340, and 360 cubic-inch small blocks nestled between its A-Body frame rails. With our Gen III Hemi swap systems, you can drop some late model Mopar muscle in there too.

The Chrysler Gen III Hemi engine is quickly becoming the new high-performance swap in the performance aftermarket. We offer swap items from many of Holley's brands to help you install a Gen III Hemi engine into your favorite chassis!
