1970 Plymouth Road Runner With a 440 Six-Barrel V8 Heads to a New Owner

Few things in the collector world stir emotions like a properly sorted golden-age muscle car, and this 1970 Plymouth Road Runner currently offered for sale in Salem, New Jersey, fits that description neatly. According to the listing on eBay, the asking price sits at $46,500 or best offer, and the car has clearly drawn attention from buyers who value capability over strict originality.

The seller picked the Plymouth up roughly a decade ago as a roller, meaning it arrived without a drivetrain. That gave them freedom to build the car the way they wanted rather than preserving a numbers-matching survivor. The body was smoothed and resprayed in Rally Red, topped with a contrasting black vinyl roof that reportedly remains in as-new shape. An Air Grabber hood sits up front, most of the correct air cleaner assembly is included, and underside photographs are presented as evidence that the structure is free of rust. The seller is upfront that the finish has aged past perfection, but describes it as a strong high-end driver rather than a show piece.

Under the hood is where this Road Runner separates itself. Instead of the 383ci V8 these cars originally left the line with, the bay holds a professionally built, balanced 1970-coded 440ci HP V8 fitted with an upgraded camshaft, a correct aluminum Edelbrock intake and the Six-Barrel carburetor setup. That triple-carb arrangement was a factory option in 1970 and carried a rating of 390 horsepower and 490 ft-lbs of torque. Backing the big-block is a four-speed manual transmission and a 4.56 Posi rear end, both installed in 2016, along with an aluminum radiator, air shocks and a dual exhaust that retains the original manifolds. Power steering and power front disc brakes round out the package, and the seller reports only about 150 miles covered since the build was completed.

Inside, the cabin was fully retrimmed during the refresh and shows almost no wear thanks to how little the car has been used since. Upholstery, carpet, dashboard and pad all present cleanly. A Sunpro Super Tach II is the lone obvious aftermarket touch, which is a curious addition given that the car already carries the desirable factory Tick-Tock-Tach. A sports steering wheel, pistol-grip shifter and the original AM radio with 8-track player are all part of the deal.

Purists may note that this Road Runner is no longer numbers-matching, and that is precisely the trade-off being offered here. The original 383 would have been quick in its day; the 440 Six-Barrel under the hood today is simply quicker. With the listing already generating strong interest and a buy-it-now figure that reads as realistic for the specification, this Plymouth looks well positioned to find a new garage soon.
