426 Max Wedge-Powered 1963 Plymouth Belvedere

Description

In the early 1960s, drag racing’s spotlight fell on Top Stock Eliminator, where large Super Stock fields battled and by 1963 Dodges and Plymouths often led. Their advantage centered on the 426 Max Wedge, offered in 415-horsepower street/strip and 425-horsepower race versions with high compression, dual Carter carburetors, and a cross-ram intake. Installed in lighter unit-body cars, these engines delivered superior power-to-weight performance.

Chrysler racers favored the durable A727 TorqueFlite automatic with push button gear selector for better traction and faster shifts. Importantly, these proven combinations were available to customers making 1963 Plymouths formidable competitors.

This Belvedere was built at automaker's Los Angeles plant in January 1963. It has been modified with an RB 440ci V-8 Wedge engine with a date code of May 7, 1966. In the style of a Super Stock racer, the engine features an aluminum Max Wedge Cross Ram intake with twin Carter 750-cfm carburetors, and the car is equipped with a 727 TorqueFlite automatic transmission with push button gear selector. In a further detail nod, the hood features the signature Max Wedge scoop.

This 426 Max Wedge-Powered 1963 Plymouth Belvedere is now offered by the executor of the late owner's estate with an owner's manual and a clean California title.
