Story
The 1963 Plymouth Savoy Max Wedge belongs to Plymouth's Super Stock 426 program, not to a single Savoy-only trim. Reviewed records place the package across eligible Savoy, Belvedere, Fury, and Sport Fury bodies. This page keeps those factory series and body choices together rather than turning each configuration into a duplicate car page.
Two factory engine choices
The short-ram, dual-quad 426 used a 4.25-inch bore and 3.75-inch stroke. The 11.0:1 version was rated at 415 gross horsepower and 470 lb-ft, while the 13.5:1 version was rated at 425 horsepower and 480 lb-ft. Both were Super Stock 426 configurations.
Plymouth revised the engine during the model year. Factory bulletin 63-26B identifies the later 426-II by starting engine numbers, a -2 engine-number form, and a Roman numeral II on the valve covers. Revised carburetors, heads, camshaft, clutch, converter hardware, and cooling details belong to that production change, not to a separate car model.
Built around acceleration
The factory transmission choices were the heavy-duty T-85 three-speed manual and A727 TorqueFlite. A later four-speed is common in modified cars, but the reviewed Plymouth bulletin does not establish one as a 1963 Super Stock 426 factory path. The package used 3.91 Sure-Grip gearing, torsion-bar front suspension, rear leaf springs, lightweight 10-inch manual drum brakes, and high-flow exhaust.
Some surviving Savoys wear aluminum front panels, but the evidence must remain car-specific. The documented race car in the reviewed history received its aluminum front later, so aluminum bodywork alone cannot establish how another car left Plymouth.
Paperwork establishes identity
A cross-ram 426, scoop, badges, later four-speed, or restored race appearance can be added to another Plymouth. Authenticate an individual car by reconciling its body tag, IBM card or broadcast sheet, engine and transmission evidence, axle, paint and trim, dealer records, and ownership history.
