1970 Plymouth Road Runner Superbird 440
Dubbed the ‘Aero Warrior’, the Plymouth Superbird was a sister car to the Dodge Charger Daytona. Both cars were sold with huge nose cones and rear spoilers that made them legendary among the competition. These were the first stock cars to be modified aerodynamically.
The Superbird was made to dominate stock car racing and elevate Plymouth’s race credentials at the same time. These modifications helped the car beat the Ford Torino Talladega at NASCAR.
Due to homologation requirements, both Dodge any Plymouth had to produce the Areo Warriors in substantial numbers. In Plymouth’s case, 1,920 Superbirds had to be made and they were all built in 1970. It was based off the standard Road Runner which featured cartoon character stickers and a ‘beep-beep’ horn.
While the race versions got full blown Hemi engines, most of the Superbirds got 440 Super Commandos or 440 six-packs rated at 385hp. Of the 1920 cars made, only 93 got the Hemi 426. These were conservatively rated at 425 bhp at 4500 rpm, but actually peaked at 5800 rpm producing 550 bhp.
Our feature Superbird is all original. It features the very rare and original numbers matching 440 Six Pack engine. This car is NOT a re-creation, but a real “V” Code Superbird. One of very few built. It still has all of its original body panels with VIN stamps on them. It has only 65,000 miles on it.
