Vehicle Story

This 1970 Plymouth Superbird is a lifelong Texas car that was the recipient of a recent high-level restoration to factory condition by Restorations By Julius. Finished in its original shade of Lemon Twist Yellow over black vinyl interior, its powered by a 440ci V8 engine that has been stroked to 505ci and paired with a four-speed manual transmission. Produced only in 1970 for NASCAR homologation, this Superbird is one of an estimated 1,935 total produced with less than half of those equipped from the factory with a 4-speed manual transmission. The current owner acquired the car approximately 3 years ago in project state, with the previous owner having purchased the car in 1980. Since completion of the restoration, this Superbird only has 20 miles and is now offered with a clean Texas title. 

The car was refinished in its original shade of FY1 Lemon Twist Yellow as part of a comprehensive restoration to original condition. Based on Chryslers "B platform", it features a black vinyl roof along with the aerodynamic steel nose cone and 24" rear wing, all of which is standard equipment for the Superbird. Decals include a black "Plymouth" script along the rear quarters and the Warner Brothers Roadrunner cartoon character at the base of the rear wing. The nose cone houses pop up dual headlights with the Roadrunner cartoon character featured on the driver's side. A mesh grill covers the lower air inlet housed between the turn signals, and a chin spoiler is equipped as well.  The restoration was performed by the seller and is photo-documented; since completion the car has only been driven 20 miles.

Factory 15” Rallye wheels with trim rings are mounted on Goodyear Polyglas white-letter tires on all four corners.  Stopping power is provided by power disc brakes in the front and drums in the rear, from the factory all Superbirds came equipped with a dual master cylinder to allow the front and rear systems to operate at the same time, yet independent of each other. The factory front suspension consists of non-parallel control arms with torsion bars, heavy-duty shocks, and swaybar, the rear uses heavy-duty leaf springs.

The interior features factory upgraded bucket seats with a center console housing the shifter. The seats were reupholstered in factory-correct black vinyl and new black carpet was installed. The center console features a simulated wood grain inlay as does the handle for the "pistol grip" shifter. The three-spoke steering wheel features an inner trim ring for the iconic "meep meep" horn and center with Roadrunner cartoon graphic. A full-size Goodyear spare tire is housed in the trunk along with a correct style bumper jack and trunk mat.

Instrumentation includes a 150-mph speedometer, fuel gauge, temperature gauge, oil pressure gauge, and amperage gauge.  The five-digit odometer reads 39k miles, of which about 20 miles have been added by the seller over three years of ownership. An original style radio is fitted in the center, below the controls for the heater and the passenger side contains a lockable glove compartment.

The 440ci V8 engine block is not original to the car, but it is date-code-correct per the seller. Originally equipped with a 4 barrel carburetor, the engine is now equipped with a Six-Pack 3x2 carburetor setup, aluminum heads and a stroker crankshaft increasing displacement to 505ci.  The valve covers and air cleaner are finished in the correct gloss orange with factory decals fitted. Power is transferred to the rear wheels through a  heavy-duty 4-speed manual transmission to the Dana rear end with 3.54:1 differential.  All hardware and hoses are factory original style with correct plating and markings.

The underside has been fully restored with all components being repainted or replated to factory-correct standards and features a dual exhaust. Additional photos can be viewed in the gallery.

Having spent its entire life in Texas, this freshly restored Superbird is now offered with an original broadcast sheet, original trim tag (confirm w/ seller), and photos documenting the restoration.

@Julius – Yes it is under coated, that’s the way it came From the factory. No need for a rotisserie ...

Was the car born with J55 undercoating from the factory?
