The 1970 Plymouth Road Runner Convertible represents one of the final peaks of the original muscle car era. By 1970, the Road Runner had matured with updated styling while maintaining its playful, high-performance identity. This specific example is a rare convertible variant, offering a level of exclusivity that hardtop models simply cannot match. It has undergone an extensive frame-off restoration to return it to a factory-fresh appearance. Finished in the iconic and loud Sassy Grass Green, the car demands attention on any road or auction stage. It successfully captures the spirit of the “High Impact” color movement that defined Plymouth’s marketing strategy. Crossing the block at Kissimmee 2026 as Lot T82.1, it stands as a premier example of Mopar heritage. The car features a matching-numbers drivetrain, making it a significant find for discerning collectors. It remains a definitive statement of speed and personality from a legendary year in American automotive history.
High-Impact Sassy Grass Green and Transverse Stripes
Visual presence is the primary strength of this 1970 Plymouth Road Runner Convertible. The Sassy Grass Green paint is vibrant and deep, highlighting the car’s refined and aggressive body lines. Black transverse stripes run across the rear decklid, providing the perfect contrast to the bright neon finish. A power-operated black convertible top allows for a quick transition from a sleek profile to an open-air cruiser. The chrome bumpers and trim have been polished to a mirror shine as part of the total restoration. Correct wheels and tires ensure that the car maintains its period-accurate stance and aesthetic. Furthermore, the 1970 model year featured a redesigned grille and “Air Grabber” hood options that looked incredibly mean. This car retains all the subtle badges and decals that enthusiasts look for in a high-level build. It is a stunning visual package that looks just as fast standing still as it does at full throttle. This color remains one of the most sought-after shades in the entire Mopar catalog.
Pistol Grip Shifter and Vintage 8-Track Interior
Inside the cabin, the 1970 Plymouth Road Runner Convertible features a classic and functional black vinyl environment. The vinyl bench seat offers a traditional feel that reminds the driver of the car’s utilitarian roots. However, the centerpiece of the interior is the famous Hurst Pistol Grip shifter rising from the floor. This iconic handle provides a tactile and mechanical connection to the four-speed manual transmission. The dashboard is equipped with a factory tachometer to monitor engine performance during spirited driving sessions. For entertainment, an AM radio remains in place alongside a period-correct 8-track player for total nostalgia. Every gauge and switch has been refurbished to ensure a reliable and authentic user experience. The black interior provides a grounded contrast to the wild exterior paint, creating a balanced aesthetic. It is a space designed for the serious driver who appreciates the raw, unrefined energy of the seventies. This cockpit is a time capsule that brings the golden age of muscle back to life.
383 CI V-8 Engine and 4-Speed Manual Performance Specs
Performance for this 1970 Plymouth Road Runner Convertible is driven by its matching-numbers 383 CI V-8 engine. This powerplant was a staple of the Plymouth lineup, known for its incredible durability and significant torque output. The engine breathes through a four-barrel carburetor and delivers a deep, resonant exhaust note that defines the era. It is paired with a four-speed manual transmission, giving the driver total control over the 383’s power band. This combination was factory rated at 335 horsepower and 425 lb-ft of torque when it was new. The frame-off restoration included a full mechanical overhaul to ensure the drivetrain operates as smoothly as it looks. Underneath, the heavy-duty suspension and braking components have been refreshed for modern road safety. This car offers the kind of visceral, mechanical feedback that modern performance vehicles have largely filtered out. It is a pure, high-torque machine built for the street and the drag strip alike. This drivetrain remains a favorite for enthusiasts who value simplicity and raw strength.
