The 1969 Plymouth HEMI Road Runner was one of the most exciting Mopar muscle cars to hit the drag strip. Following the success of the Plymouth Road Runner’s 1968 debut, Sox & Martin expanded their racing lineup with a Road Runner built specifically for the Modified Production (B/MP) class in 1969. This car quickly became a standout in NHRA and AHRA competition, showcasing both Chrysler engineering and Sox & Martin’s racing expertise.
Building the 1969 Plymouth HEMI Road Runner
After dominating with their 1968 Super Stock HEMI Barracuda in SS/B and A/MP, Sox & Martin constructed a new 1969 HEMI Road Runner tailored for B/MP rules. The Modified Production (also known as Street Eliminator) class allowed more flexibility in modifications, giving the team an opportunity to push performance even further.
Under the hood, mechanic Jake King installed a high-compression Super Stock Race HEMI engine paired with a cross ram intake for maximum power. To optimize airflow, the team added an “RO” style Super Stock hood scoop to the factory Road Runner hood, giving the car both function and aggressive style.
Racing Success in 1969
The 1969 Plymouth HEMI Road Runner made an immediate impact on the drag racing scene. At the 1969 AHRA Winter Nationals, Ronnie Sox’s powershifting skills helped the Road Runner take victory in B/MP, cementing the car as a serious contender. Throughout the 1969 NHRA and AHRA seasons, this Road Runner remained a constant threat in its class, further spreading Chrysler’s presence in multiple competition categories.
Why the 1969 HEMI Road Runner Stands Out
The 1969 Plymouth Road Runner HEMI wasn’t just another Mopar muscle car—it represented a strategic move by Chrysler and Sox & Martin to diversify their dominance across different racing classes. Collectors and enthusiasts celebrate this car for its:
Legendary 426 HEMI race engine with cross ram intake
Unique Modified Production (B/MP) setup
Iconic Sox & Martin red, white, and blue livery
Proven success at national events like the AHRA Winter Nationals
Role in cementing the Road Runner’s reputation as a drag racing powerhouse
Legacy of the 1969 Plymouth HEMI Road Runner
Today, the 1969 Plymouth HEMI Road Runner stands as one of the most celebrated drag racing Mopars of the late 1960s. Combining Chrysler engineering, Sox & Martin innovation, and Jake King’s engine mastery, this Road Runner proved that Mopar muscle could dominate across multiple classes.
