The 305-powered 1940 Plymouth Roadking stands as a raw street rod that blends vintage styling with purposeful mechanical upgrades. This build highlights performance-focused changes that push the classic two-door sedan into modern territory.
Street Rod Character with a Blacked-Out Look
The body was spray-painted black after removing the bumpers, trim pieces, and lower grille slats. A split windshield, grille-mounted turn signals, and aftermarket taillights give the car a stripped, almost industrial attitude.
Wheels, Tires, and Lowered Stance
Black 15-inch steel wheels with polished hubcaps sit under the lowered suspension. The setup uses shortened front coils and rear lowering blocks, while new Milestar tires were installed during recent service.
Interior Focused on Utility
The cabin remains bare but functional with vinyl bench seats, a fabric headliner, and a floor shifter. A three-spoke wheel fronts a 120-mph Police Special speedometer and auxiliary Autogage instruments.
Odometer and Driver Information
The five-digit odometer shows roughly 400 miles, representing the distance recorded under current ownership, though the true mileage is unknown.
Power, Engine Specs, and Performance
The Chevrolet 305ci V8 leads the mechanical upgrades, supported by Edelbrock components including the carburetor, air cleaner, intake, and valve covers. A three-speed automatic transmission feeds power to a Dodge Charger rear axle through an Oldsmobile driveshaft. Dual side-exit exhausts with glasspack mufflers deliver a sharp tone and quick response.
Recent Mechanical Work
Recent servicing included a carburetor rebuild, new fuel pump and filter, an oil change, and replacement of the trunk-mounted battery and its hardware. The updates support reliability and ease of use.
Additional Mechanical Details
The conversion to a 12-volt system enhances ignition performance and electrical stability. Together, these changes help modernize the driving experience without removing the car’s vintage feel.
Summary
This 305-powered 1940 Plymouth Roadking offers a rugged, modified take on a classic sedan. With its blacked-out exterior, simplified interior, and performance-focused upgrades, it presents a distinctive street rod built for character rather than perfection.
