Introduction: The Plymouth Super Bird was created for the same reason as the
Dodge Daytona -- a full on high speed race machine designed for the NASCAR races,
but available to the public.
1970 Plymouth Super Bird
Comments: Trying to capture some of the success that their Dodge brothers had in 1969
with their Daytona, Plymouth tried the same thing in 1970 with their creation, the
Plymouth Superbird. Although similar in appearance, the Superbird was actually
quite different from the Daytona. The Superbird was based on the Plymouth
Road Runner and the nose, airfoil, and basic sheet metal was different between the
Daytona and Superbird. The special nose added 19 inches to the overall length (the
Daytona's was 18 inches), and the trunk spoiler was more angled and higher than the
Daytonas. On both models, the spoiler was two feet high so that the owner could
open the trunk. Although it created quite an impression on the street, the
wing did almost no aerodynamic good under 90 mph.
NASCAR only required 500 copies to be built in 1969, but in 1970, NASCAR required a
manufacturer to build one unit per dealer. In the end, Plymouth built
a total of 1,920 SuperBirds. SuperBirds were available with three different engines. The
most popular was the basic Super Commando 440 V8 with a single four barrel carb rated at
375 bhp. Next up was the 440 Six Pack rated at 390 bhp. At the top, and ordered by just
93 buyers, was the mighty 426 Hemi, rated at 425 bhp. Despite the success of the SuperBird
on the tracks, 1970 would be the only year it was made.
426 V8 Hemi 425 bhp @ 5000 rpm, 490 lb-ft @ 4000 rpm.
440 V8 375 bhp @ 4600 rpm, 480 lb-ft @ 3200 rpm.
440/390: 0-60 in 5.9 seconds, 1/4 mile in 14.26 seconds @ 103.7 mph.
426/415: 0-60 in 4.8 seconds, 1/4 mile in 13.50 seconds @ 105.0 mph.
