1972 Plymouth Roadrunner

A true icon of the muscle car era, this 1972 Plymouth Road Runner offers the perfect combination of classic Mopar design, performance-driven upgrades, and show-stopping curb appeal. Finished in its factory-correct Petty Blue (also known as Basin Blue), this Road Runner stands out from the crowd and stays true to its roots, while incorporating a number of tasteful enhancements that elevate both drivability and visual impact.

Under the hood sits a date-correct 400 cubic inch V8, professionally built with performance in mind. This is the desirable “cold weather” block — known for its thicker main webs and stronger casting — paired with an automatic transmission upgraded with a manual valve body for crisp, old-school shifting. The engine features an Edelbrock 750cfm carburetor, an Edelbrock intake manifold, 440 Source aluminum heads, and a Mopar “Purple” camshaft. The addition of headers completes the performance package, producing a deep, unmistakable exhaust note that Mopar fans will instantly recognize.

With just 48,000 miles (TMU), this Road Runner remains remarkably solid. The seller reports that the car is virtually rust-free, with the exception of a single small area on the driver’s side floor, which has been internally patched and remains structurally sound. A few cosmetic imperfections are noted — including minor chrome peel on the front bumper, a small dent near the center of the hood, and light blistering in the paint near the left boomerang — but overall, the body is straight and presents beautifully for its age.

The Road Runner’s aggressive stance is further enhanced by factory-correct styling details including the boomerang hood scoops, front chin spoilers, and a rear decklid spoiler. It rides on classic Magnum-style wheels wrapped in BF Goodrich Radial T/As — 215/60R15 in the front and 275/60R15 in the rear — for a period-authentic muscle car look. A brand-new power brake booster and reservoir have been added for improved braking feel, and the car benefits from front disc brakes for added stopping confidence.

Inside, the black interior has been fully refreshed, featuring new bucket seat upholstery, new carpet, and replacement seat belts, including factory-style shoulder belts. The cabin is clean and complete, with no major damage to the trim or panels. The original radio still powers on (though speaker output is currently non-functional), and the temperature gauge reads inconsistently — small quirks in an otherwise well-preserved interior. The classic center console and factory shifter add to the sporty, driver-focused vibe of the cockpit.

Mechanically, the Road Runner has seen several recent updates to ensure it runs and drives as well as it looks. These include a new steering box, a new power steering pressure line, fresh oil and plugs, and a new ballast resistor. A professional front-end alignment was also completed, enhancing both ride quality and steering response. This is a car that’s been thoughtfully maintained, with smart performance and reliability improvements made over time.

This particular example decodes as a true RM23-coded Road Runner — a genuine two-door hardtop built at the St. Louis assembly plant, equipped from the factory with the high-performance 400ci 4-barrel V8. It’s a model that represents the last of the true muscle cars before the industry-wide shift to emissions regulations and insurance constraints in the mid-1970s.

Whether you’re a Mopar purist, a classic muscle car enthusiast, or a collector looking for a solid and stylish investment, this 1972 Plymouth Road Runner delivers. With its factory Petty Blue paint, clean body, performance-built drivetrain, and modern drivability upgrades, it offers an ideal balance between originality and usability — a car you can enjoy today, and continue to improve or preserve over time.
