The 1973 Plymouth Road Runner 340 represents a fascinating chapter in the evolution of the American muscle car, arriving just as the industry pivoted toward a balance of luxury and performance. This example, finished in its factory-correct Honey Gold, serves as a testament to the enduring appeal of the B-body platform. Under current ownership, the vehicle has undergone significant mechanical refreshment, ensuring that its rebuilt powertrain is supported by a modernized suspension and reliable cooling systems. Offered at no reserve, this Road Runner retains its quintessential “Beep-Beep” personality while offering the drivability expected of a well-sorted classic.
Honey Gold Aesthetics and Performance Styling
The exterior of this Road Runner is finished in JY3 Honey Gold, a period-perfect hue accented by black longitudinal side stripes that arch dramatically over the roofline. The bulged performance hood features matching black accents, emphasizing the car’s aggressive silhouette. While the body showcases an honest patina with some chips and minor rust, the core identity of the 1973 model is preserved through quad headlights, fender-mounted turn-signal monitors, and chrome bumpers with rubber overriders. It sits authoritatively on 15-inch American Racing Torq Thrust wheels wrapped in BFGoodrich Radial T/A tires, a classic combination that enhances its vintage stance.
Gold Vinyl Cabin and Slap Stik Control
The interior is a time capsule of 1970s Mopar design, featuring high-back front bucket seats and a rear bench upholstered in buttoned gold vinyl. A center console with woodgrain trim houses the iconic Slap Stik shifter, allowing for precise control over the three-speed automatic transmission. Modern conveniences have been subtly integrated, including a Bluetooth-capable retro-look radio and aftermarket speakers. Maintenance since 2020 has included the replacement of the headliner and carpeting, ensuring a clean environment for the driver. The Tuff steering wheel fronts a full suite of instrumentation, including a 7k-rpm tachometer and a 120-mph speedometer.
Rebuilt 340ci V8 and TorqueFlite Dynamics
Motivation comes from a 340ci V8 that was rebuilt under previous ownership and further refined with a rebuilt Carter four-barrel carburetor in late 2024. This engine produces 240 hp/243 PS and 295 lb-ft/400 Nm, delivering power to the rear wheels through a replacement TorqueFlite three-speed automatic transmission equipped with a 3,500-rpm stall converter. To ensure reliable performance, the current owner replaced the alternator, voltage regulator, and ignition-control module. The suspension was also completely overhauled in 2024 with new shocks, ball joints, and a pitman arm, while power-assisted front disc brakes provide modern stopping confidence.

Positioning the 1973 Road Runner in Today’s Market
The 1973 model year serves as a unique entry point for Mopar enthusiasts, often offering a more accessible price point than the earlier 1968-1971 “Aero” cars while retaining the same mechanical DNA. Compared to rivals like the Chevrolet Chevelle or Ford Torino of the same era, the Road Runner 340 maintains a distinct “bad boy” image thanks to its cartoon-inspired branding and performance-oriented options. With factory documentation like the broadcast sheet and build sheet included, this example stands as a transparent investment. The recent extensive mechanical servicing adds significant value, making it a reliable choice for regional car shows and weekend tours.
Legacy of the B-Body Muscle Machine
This 1973 Plymouth Road Runner 340 successfully bridges the gap between a high-performance muscle car and a usable vintage cruiser. Its combination of rebuilt mechanicals, classic Honey Gold styling, and documented history ensures that it will remain a centerpiece of Mopar culture for years to come.
