A Mr. Norm–Built Legend: 1973 Plymouth Duster 340 Paxton Supercharged

Few muscle cars capture the spirit of early-’70s Mopar performance quite like the 1973 Plymouth Duster 340—and this example elevates that legacy to an entirely different level. Built by the legendary Mr. Norm, this Duster is a rare blend of originality, period-correct performance, and documented craftsmanship.

At its core is the factory-born 340 cubic-inch V8, paired with a 4-speed manual transmission, delivering the raw, driver-focused experience that made Mopar muscle famous. Showing 64,000 original miles, the car retains the authenticity collectors seek, while benefiting from a carefully executed performance rebuild.

The engine itself has logged just 2,500 miles since its build, featuring a custom-ground camshaft by Howard’s Cams, designed specifically to complement the forced-induction setup. Topping the combination is a Paxton supercharger, fully rebuilt and showing less than 100 miles, providing instant throttle response and period-correct boost without sacrificing drivability.

What truly sets this Duster apart is its direct connection to Mopar royalty. Mr. Norm’s signature is etched directly into the valve covers, a subtle yet powerful mark of authenticity that confirms the car’s heritage and elevates it from a modified muscle car to a true collector piece.
