The Duster was Plymouth’s affordable compact performance car, and this one has been upgraded with a larger V8 and a fresh round of parts. The current owner has fitted a Holley carburetor, an aluminum intake, Scat Procar seats, and a Hurst shifter, and replaced the brakes, mounts, seals, and grille. Bidding stands at $8,999 with three days remaining and eight bids placed.

What it’s worth right now
Data from Conceptcarz places a 1972 Duster in good condition between $14,850 and $20,900, with excellent examples from $20,900 to $30,800. Dealers have recently asked $36,900 and $39,900 for other 360-powered 1972 Dusters.
The engine swap and recent work place this one in the good-condition band. The rebuilt 360, the fresh parts, and the documentation help, while the swapped engine, loose window regulators, roof bubbles, and paint chips hold it below the stronger examples, and modifications rarely return their cost. Fair value lands between $18,000 and $26,000, with $22,000 most likely. The current bid of $8,999 has three days to run against a reserve.

Condition and details
The drivetrain has been refreshed. The 360, installed in 2020, is rebuilt with a performance camshaft and an aluminum radiator, and the current owner added a Holley 650-cfm carburetor, an aluminum intake, an HEI distributor, and a new alternator, rear main seal, gaskets, hoses, and mounts. The TorqueFlite is rebuilt, and a new torque converter was fabricated.

The chassis and cabin are updated. The car rides on 14-inch front and 15-inch rear Rallye wheels with front and rear anti-roll bars, and the brakes were refurbished with resurfaced rotors, new front pads, and new rear wheel cylinders. Inside are Scat Procar buckets in white vinyl installed in August 2026, a Hurst shifter, a white rear bench, and a JVC stereo.

A few items need attention. The seller notes the window regulators are loose and rattle, the vinyl roof has bubbles, and the paint shows chips. The fender tag decodes to an original 318 and white bench seat, so the engine and seats are not factory. A broadcast sheet, records, and a brochure accompany the sale, and the California title is clean. A pre-purchase inspection should check the floors and the rear axle.

What makes the Plymouth Duster unique
The Duster arrived for 1970 as a fastback coupe built on the Valiant platform. Its light A-body made it quick with V8 power, and the 340-powered versions became genuine performance bargains. Most Dusters, like this one, left the factory with the 318 or a slant six.

Engine swaps are common and widely accepted. The 360 shares its mounts with the 318 and offers more torque, making it a popular upgrade that keeps the car’s character. Original 340 cars command the highest prices, while well-sorted 360 swaps offer much of the experience for less.
My take
At $8,999 with eight bids and three days to run, my call is $22,000, with $26,000 possible if bidders value the fresh parts and the Tor-Red paint. What makes it appealing is the combination, since a Tor-Red Duster with a rebuilt 360, a rebuilt TorqueFlite, and new brakes is a fun, usable Mopar. What tempers it is the needs list, because the window regulators, roof bubbles, and paint chips call for attention. Budget for the cosmetic work, then bid.
