Rare muscle cars often come with a story, but few can match the production numbers of this 1970 Plymouth Road Runner Convertible. It stands as one of only twenty examples ever built for that model year featuring the massive 440ci V8 with a Six Pack induction system. This Canadian-market survivor spent approximately thirty-five years in storage before recently emerging to join the collector market once again.
The Aggressive Stance of a Blacked Out Muscle Icon
While originally delivered in Ivy Green, this 1970 Plymouth Road Runner Convertible was refinished in a deep black paint decades ago. This color change enhances the intimidating profile of the car, especially when paired with the power-operated black convertible top. Road Runner graphics and the signature dual exhaust outlets give it a presence that few other vintage convertibles can hope to replicate.
Classic Rallye Wheels and Goodyear Polyglas Tires
The vehicle sits correctly on fifteen-inch Rallye road wheels that provide a perfect period-correct look. These wheels are mounted with Goodyear Polyglas tires, which were the standard for performance back in the early seventies. Interestingly, both the steering and the four-wheel drum brakes remain unassisted on this build. This configuration requires a steady hand and offers a truly raw connection between the driver and the road.
A Driver Focused Cabin with Pistol Grip Precision
Inside the 1970 Plymouth Road Runner Convertible, the black vinyl theme continues across the front bucket seats and rear bench. The center console is accented with woodgrain trim, housing the famous Hurst pistol-grip shifter that every Mopar enthusiast recognizes. A unique tic-toc tachometer sits in the dash, combining a clock and RPM gauge into one functional unit for the driver.
Track Pak Performance and Canadian Heritage
This specific car was built to Canadian order specifications, making its survival even more impressive given the northern climate. It features the A33 Track Pak, which includes a heavy-duty cooling system and a Sure-Grip limited-slip differential. The 3.54:1 rear gear ratio ensures that the car can effectively put its massive torque to the pavement during hard acceleration.
Engine Performance and Six Pack Specifications
The heart of this beast is the 440ci V8 engine topped by three Holley two-barrel carburetors, a setup famously known as the 440+6. This combination was factory rated at 390 horsepower and a staggering 490 lb-ft of torque. It is backed by a rugged four-speed manual transmission that allows the driver to row through the gears manually. This drivetrain represents one of the most powerful and sought-after configurations from the classic muscle car era.
Summary of a Truly Rare Mopar Survivor
A 1970 Plymouth Road Runner Convertible with these mechanical specs is a prize that rarely becomes available to the public. Its history of long-term storage has helped preserve the character of a car that was built for high-performance duty. Whether you value the production rarity or the raw power of the Six Pack V8, this car delivers on every front. It remains a definitive piece of American automotive history that continues to command respect.
