Never Was: Custom 1971 Plymouth HEMI® Superbird Going To Mecum

Build Using Chrysler Aero Study Blueprints...

The 1970 Plymouth Superbird was one of the most unique vehicles ever built, with its iconic nose cone and towering rear wing. However, many people do not know that Chrysler had a successor on the drawing board that was never released – until now.

Thanks to the work of a team of dedicated enthusiasts, the 1971 Plymouth Superbird that never was, has finally been brought to life. Using only the engineering blueprints from the Chrysler Aero study, wind tunnel testing, and 3/8 scale models of the G-series/1971 body styles, this full-scale rendering represents the only true and accurate version of the canceled design.

The most apparent changes from the 1970 Superbird are the electrically operated headlight doors, fender air extractor scoops, and the rear wing designated as the optimum design aerodynamically. However, the project is not just about appearances – the car features a 7.7-liter (472 cubic-inch) Mopar Performance HEMI® V8 engine with a Tom Hoover-inspired Six Barrel setup, good for 570 horsepower.

The engine is paired with an American Powertrain 5-speed manual transmission with overdrive and a factory 3.54 Sure Grip Dana 60 rear end. The car also boasts power steering, .96 front torsion bars, Mopar Performance rear leaf springs, HD front and rear sway bars, and 4-wheel power disc brakes.

The blacked-out rear valance has been customized to accommodate rear quad Bazooka exhausts featured on Chrysler’s factory concept cars for 1971. This attention to detail has earned the car features in Hot Rod, Mopar Collector’s Guide, and Mopar Action Magazines.
