could it be a ram-charger?
"Beginning around April of 1962, Dodge and Plymouth offered the first Maximum Performance Wedge (nicknamed Max Wedge) in their new, light, mid-sized cars. The '62 Max Wedge had a 413 cubic inch engine. The engine was enlarged to 426 c.i. for 1963 and 1964. The Max Wedge package, which included many drivetrain and chassis modifications, was available in all 1962, 1963 and 1964 B-body Dodges and Plymouths (330, 440, '62 Dart, Polara, Polara 500, Savoy, Belvedere, Fury, Sport Fury), except 1962 station wagons. Dodge called the package "Ram-Charger 413/426", Plymouth called it "Super Stock 413/426". Mid-year '63 saw the addition of aluminum body panel options including an optional hood scoop, a trunk-mounted battery to add more weight over the rear axle and the "Stage II" Max Wedge engines. The 1964 engines were labeled "Stage III". Contrary to popular belief, neither the early '63 426 nor the '62 413 were ever called "Stage I"
