This awesome 5.7-liter HEMI®-powered 1971 Plymouth Duster is currently up for auction on the popular automotive auction site BringATrailer.com. Finished in the ever-so-striking Snakeskin Green with Black graphics, the classic A-body Mopar blends retro aesthetics with modern performance upgrades.

Performance Upgrades – 

Originally featuring a 5.2-liter (318 cubic-inch) 2-barrel V8 when it left the factory, this Duster is now equipped with an impressive 5.7-liter (345 cubic-inch) HEMI® V8 engine, installed by a previous owner. The engine bay has also been smoothed and refinished. Notable features include:

• Fuel Air Spark Technology (FAST) electronic fuel injection
• Mopar Performance air cleaner
• Indy Cylinder Head Mod Man intake manifold
• Tubular headers
• An aluminum radiator equipped with dual electric cooling fans

The seller reports recent maintenance, including the replacement of fuel injectors, fuel pump, fuel filter, and spark plugs and servicing the cooling system. The timing curve has been modified, and the rev limiter is set to 6,500 rpm for enhanced performance. Power is delivered to the rear wheels through a modified three-speed automatic transmission with a manual valve body.

Eye-Catching Exterior –

Originally painted in Sherwood Green Metallic (GF7), the Duster was repainted in Snakeskin Green Pearl, the same color found on the 2010 and 2017 Dodge Viper, under previous ownership. Key exterior features include:

• A twin-scoop hood with external latches, finished in flat black
• Chrome bumpers and frameless door glass
• Pop-out rear quarter windows

It sits on 17-inch black aftermarket wheels, fitted with 205/50 Toyo Extensa HP tires in the front and 315/35 Toyo Proxes TQ drag radials in the rear. The braking system features Wilwood disc brakes with cross-drilled and slotted rotors, while the front suspension is enhanced with QA1 coil-overs and rack-and-pinion steering.

Stylish Interior –

Inside, the Duster showcases a blend of comfort and performance:

• Scat Procar bolstered front bucket seats and a rear bench, all trimmed in black upholstery
• An Alpine CD player with Bluetooth connectivity
• A FAST EFI control module mounted on the dash

The interior features AutoMeter instrumentation, including a 160-mph speedometer, a 10k-rpm tachometer, and additional auxiliary gauges. Other notable features include a Cheetah SCS shifter, aftermarket kick panels with speakers, and latch-and-link front lap belts.

This 1971 Plymouth Duster combines classic styling with modern performance enhancements, making it an exciting prospect for car enthusiasts.
