The 1972 Plymouth Duster holds a special place in drag racing history as one of the most famous Mopar Pro Stock cars ever built. After a dominant 1971 season, where Sox & Martin’s HEMI-powered ‘Cuda won nearly every NHRA Pro Stock race, the rules changed dramatically in 1972. To restore parity, NHRA forced Chrysler Pro Stockers like the Plymouth Duster to carry more than 200 extra pounds compared to their Chevrolet and Ford rivals.
Building the 1972 Sox & Martin Plymouth Duster
After early struggles with their updated ‘Cuda, Sox & Martin returned to their North Carolina shop and began constructing a new 1972 Plymouth Duster Pro Stock. Starting from a Body-In-White, the car was acid-dipped to cut weight. Compared to the ‘Cuda, the Plymouth Duster was narrower and offered better aerodynamics, giving the team an edge despite NHRA’s new restrictions.
Equipped with all the latest chassis and suspension advancements, and powered by Jake King’s meticulously prepared 426 HEMI, the 1972 Sox & Martin Duster quickly became one of the most advanced Mopar drag cars of its era.
Performance and Racing History
Even with NHRA’s heavy-handed rule changes, the 1972 Plymouth Duster Pro Stock proved highly competitive. While Sox & Martin faced challenges in NHRA events due to the added weight penalties, they found more success in IHRA races, where rules favored the HEMI engines.
This strategic shift allowed the team to showcase the full potential of the 426 HEMI-powered Duster, cementing its place as a fan-favorite and a symbol of Mopar’s never-back-down racing spirit.
