Some cars are carrying that everlasting beauty deep within their looks and character, which is impossible to disappear or fade away, no matter how much things have changed in the meantime. With their specific design, combined with the rich history, they make the butterflies inside the stomach of the real muscle cars enthusiasts start buzzing, even from the very first moment when they appear on the scene.
And the 1970 Plymouth Road Runner Super Bird is most definitely a car that perfectly fit that description, especially because we have rare opportunities to see it. Today we are going to show you a video clip with one stunning example of the legendary Plymouth Road Runner Super Bird, with an appealing red paint job, packing 440 Super Commando engine that is giving an output to 375 HP.
Those of you who know some things from the history of Plymouth Superbird, know that this engine version means that this specimen was not one of those that were used for racing (those Superbirds were powered by 426 HEMI) but for the streets. However, that does not mean that it is not as fast as hell, and everything else that goes with it.
The Plymouth Superbird was a highly modified, short-lived version of the Plymouth Road Runner with well-known graphics and horn sound. It was the factory’s follow up stock car racing design, for the 1970 season, to the Dodge Charger Daytona of 1969, and incorporated many engineering changes and modifications (both minor and major) garnered from the Daytona’s season in competition.
The car’s primary rival was the Ford Torino Talladega, a direct response to the Mopar aero car. It has also been speculated that a motivating factor in the production of the car was to lure Richard Petty back to Plymouth. Both of the Mopar aero cars famously featured a protruding, aerodynamic nosecone, a high-mounted rear wing and, unique to the Superbird, a horn which mimicked the Road Runner cartoon character.
Superbirds equipped with the top-of-the-line 426 cu in (7.0 L) Hemi engine with a pair of four barrel Carter AFB carburettors (2x4bbl) producing 425 hp (317 kW) could accelerate from 0 to 60 mph (97 km/h) in 5.5 seconds.
Developed specifically for NASCAR racing, the Superbird, a modified Road Runner, was Plymouth’s follow-on design to the Charger Daytona fielded by sister company Dodge in the previous season.
NASCAR’s homologation requirement demanded that vehicles to be raced must be available to the general public and sold through dealerships in specific minimum numbers. For 1970, NASCAR raised the production requirement from 500 examples to one for every two manufacturer’s dealers in the United States; in the case of Plymouth, that meant having to build 1,920 Superbirds. Due to increasing emissions regulations, combined with insurance hikes for high performance cars and NASCAR’s effective ban on the aero cars, 1970 was its only production year.
On the street, the nose cone and wing were very distinctive, but the aerodynamic improvements hardly made a difference there or on the drag strip. In fact, the 1970 Road Runner was actually quicker in the quarter mile and standard acceleration tests due to the increased weight produced by the Superbird’s nose and wing. Only at speeds in excess of 60 mph (97 km/h) did the modifications begin to show any benefit.
Just watch the video and get mesmerized by the everlasting beauty of one of the most iconic muscle cars ever!
