1970 Plymouth Road Runner – 440 Supercharged Street Machine with Modern Muscle Upgrades

This 1970 Plymouth Road Runner isn’t just a tribute to muscle car heritage—it’s a fire-breathing restomod built to outrun convention. With its ProCharged 440 Big Block V8, aggressive stance, and black-on-black aesthetic, this Road Runner has been reimagined for the driver who demands both raw horsepower and modern performance.

Engine and Performance

At the core of this beast lies a monstrous 440 cubic inch Big Block V8, force-fed by a ProCharger supercharger for serious street-scorching power. It’s topped with a Demon carburetor, Mopar aluminum intake, and MSD ignition to deliver explosive throttle response and torque you can feel in your chest. Long tube headers and a dual exhaust system let it breathe with authority while unleashing a vicious soundtrack. A 4-speed manual transmission and CalTrac traction bars ensure you stay connected to the pavement, making each gear shift an adrenaline-fueled experience. Cooling is handled by an aluminum radiator with dual electric fans, while an aftermarket serpentine belt system keeps everything dialed in.

Cab and Comfort

Inside, this Road Runner blends muscle car attitude with modern comfort. The black vinyl bucket seat interior is enhanced with aftermarket seating for improved support and driving feel. AutoMeter gauges keep vital stats front and center, and a Grant GT steering wheel puts you in total command. The cabin stays comfortable thanks to a modern aftermarket A/C system, and when the exhaust note isn’t enough, the upgraded sound system provides the soundtrack to your drive. From layout to fit and finish, the interior is driver-focused and road-ready.

Features and Attachments

This Road Runner is equipped to dominate on the road and look good doing it. It rides on bold 19-inch Aodhan wheels that give it a planted, aggressive stance. Wilwood 4-wheel disc brakes provide confident stopping power, and line locks are ready for action at the strip. The classic power bulge hood and hood pins hint at its old-school roots, while Mopar Performance finned aluminum valve covers deliver the right period-correct flair. Power steering and manual brakes offer a direct, connected feel, keeping the driver engaged and in full control.

Operational Assessment

This Road Runner fires up confidently and runs strong with all major systems fully operational. Gauges—including oil pressure, fuel level, temperature, speedometer, and tachometer—are all functioning accurately. Exterior lights (headlights, brake lights, tail lights, turn signals) and wipers are in working order, as are the heater and aftermarket air conditioning. The upgraded radio system is functional and adds to the car’s cruising appeal. The only noted exception is the horn, which is currently inoperative. Beyond that, this car delivers a dependable and thrilling driving experience.

With its killer looks, high-powered supercharged V8, and thoughtful blend of modern components and classic design, this 1970 Plymouth Road Runner is far more than a nostalgic ride—it’s a full-throttle statement. Whether you’re carving up the boulevard, laying rubber at the strip, or simply collecting stares at your local show, this is a muscle machine that doesn’t just talk the talk—it backs it up with supercharged force.
