Contrary to its cartoon namesake, the Plymouth Road Runner wasn’t afraid to offer a variety of engine options during the muscle car era.
The 383 cubic-inch V8 reigned supreme, finding favor with its potent 335 horsepower at a reasonable price point. However, for those craving even more power, the 440 Six-Barrel and the legendary 426 HEMI were available.
While these bruisers boasted impressive muscle, their high insurance costs likely scared away many potential buyers, making them significantly rarer than the base 383.
Unlike the thunderous engine options that typically steal the spotlight, a seemingly unremarkable feature could propel a 1970 Plymouth Road Runner from a mass-produced muscle car to a highly sought collector’s trophy.

While the 383-cubic-inch V8 dominated the Road Runner engine bay, accounting for a sizeable 2,501 units produced, other factors significantly influenced a car’s rarity.
Look no further than the convertible body style. In 1970, a mere 658 convertibles rolled off the assembly line, and a scant 37 boasted anything more potent than the standard 38f3 engine.
Underneath the hood lies a numbers-matching drivetrain, a detail highly valued by collectors, and the exterior boasts the desirable Air Grabber hood and hood pins features typically associated with the more powerful 440 and 426 HEMI engines.
To top it all off, the white interior complements the B5 Blue paint job beautifully, creating a truly distinctive package. With its unique combination of features and limited production numbers, this 1970 Plymouth Road Runner convertible is certain to turn heads and generate excitement in the collector car market.
