This 1970 Plymouth Road Runner Hardtop is a purpose-built Mopar muscle machine that combines the legendary styling of one of Chrysler’s most celebrated performance models with the immense power of a 528ci Hemi V8 and a modern five-speed manual transmission. Extensively upgraded during a refurbishment completed under previous ownership, this Road Runner delivers the raw character of classic American muscle while incorporating performance enhancements designed to elevate the driving experience far beyond factory specifications.
Finished in eye-catching Petty Blue with contrasting white accents, the car presents with the aggressive stance and unmistakable attitude that made the Road Runner a performance icon. The cowl-induction hood features white accent treatment that complements the white Plymouth lettering along the rear quarter panels, while classic Road Runner graphics reinforce the car’s heritage. Additional exterior details include quad headlamps, chrome bumpers, dual exhaust outlets, and a driver-side mirror, creating a clean yet highly purposeful appearance that immediately signals this is no ordinary B-body Mopar.
The car rides on chrome Cragar S/S wheels wrapped in staggered Goodyear Eagle GTII tires, giving it an aggressive muscle car stance while maximizing traction. Power steering enhances drivability, and power-assisted front disc brakes provide confident stopping performance. Further performance upgrades include CalTracs traction bars, helping transfer the substantial output of the Hemi powerplant to the pavement while improving stability during spirited driving.
Inside, the cabin maintains the straightforward, driver-focused atmosphere that enthusiasts expect from a classic Road Runner. Front bucket seats and a rear bench are upholstered in black vinyl and are complemented by matching door panels, carpeting, and dashboard trim. A center console and woodgrain accents add visual refinement, while aftermarket air conditioning provides modern comfort for cruising in a variety of climates. Additional equipment includes an AM/FM radio, front and rear lap belts, front shoulder belts, carpeted floor mats, and the iconic Hurst pistol-grip shifter, one of the most recognizable features in the muscle car world.
The driver is greeted by a three-spoke steering wheel featuring a chrome horn ring and the beloved Road Runner “Beep! Beep!” center cap. Ahead sits a Rallye-style instrument cluster incorporating a 150-mph speedometer, the desirable Tic-Toc tachometer with integrated clock, and gauges monitoring fuel level, coolant temperature, oil pressure, and charging system status. The odometer currently displays approximately 2,000 miles and is reported to have rolled over, with total mileage unknown.
At the heart of the build is a formidable 528ci Hemi V8 installed during the refurbishment completed around 2012. This legendary engine configuration delivers the kind of performance that has made the Hemi name synonymous with American horsepower for generations. The engine is equipped with Mopar Hemi valve covers, a Mopar intake manifold, open-element air cleaner, MSD Digital 6AL ignition controller, and MSD Blaster ignition coil. Ceramic-coated tubular headers feed into a custom dual exhaust system with an H-pipe, producing the unmistakable sound and presence expected from a high-performance Mopar powerplant. Additional upgrades include a replacement wiring harness and a custom trunk-mounted battery box, contributing to both reliability and engine bay presentation.
Power is delivered through a Tremec five-speed manual transmission, providing a modern and engaging driving experience while allowing the Hemi’s power to be fully utilized. A Sure-Grip limited-slip differential ensures effective traction and power delivery, creating a drivetrain combination capable of handling the substantial torque produced by the 528ci engine.
Originally equipped with a 383ci V8, this Road Runner has evolved into a significantly more powerful and performance-focused machine while retaining the styling and character that made the model a legend. Combining iconic Mopar design, Hemi power, modern transmission technology, and carefully selected upgrades throughout, this 1970 Plymouth Road Runner represents an outstanding opportunity for enthusiasts seeking a highly desirable muscle car that delivers both show-stopping presence and exhilarating performance.
Whether displayed at premier Mopar events, enjoyed on weekend cruises, or unleashed on open roads, this Road Runner offers the kind of visceral driving experience and unmistakable character that continue to make Hemi-powered muscle cars among the most sought-after vehicles in the collector market.
