Story
The 1964 Dodge Polara Max Wedge was the final version of Dodge's Ramcharger 426 factory acceleration package. It was not one separate Polara trim. Dodge listed the engine for the 330, 440, and Polara lines, and the model-year range also included the Polara 500. Keeping those series and body choices on one page preserves the ordering structure instead of turning each combination into a different car.
Ramcharger 426 Stage III
The 11.0:1 engine retained its 415-horsepower and 470-lb-ft gross ratings. The high-compression version moved to 12.5:1 while retaining 425 horsepower and 480 lb-ft. Dodge's bulletin describes a revised 15-inch aluminum short-ram intake, two Carter AFB-3705SA four-barrels, larger valves, improved heads, compression-specific camshafts, stronger connecting rods, a six-quart baffled oil pan, and a fixed oil pickup.
Three transmission paths
A floor-shifted T-85 close-ratio three-speed was standard. The new A833 four-speed was optional, making 1964 the only production year for a four-speed Max Wedge. A strengthened TorqueFlite Eight provided the automatic path.
Axle calibration depended on the engine: 3.91 Sure-Grip with the 11.0:1 version and 4.56 with the 12.5:1 version. Special rear springs, heavy-duty driveline hardware, lightweight 10-inch manual drum brakes, and streamlined exhaust manifolds completed the package.
Lightweight was optional
The aluminum front-end package added aluminum fenders, hood, dust shields, and bumper supports. Its hood carried a functional scoop and air horn. It was optional equipment, not proof that every Ramcharger car was a lightweight.
Keep the engines straight
The 365-hp single-four-barrel Street Wedge and the midyear Race Hemi were separate 426 programs. A cross-ram, scoop, four-speed, badges, or restored race appearance cannot establish Ramcharger identity by itself. Authenticate a car by reconciling its body tag and Chrysler record with engine, transmission, axle, paint, trim, dealer, and ownership evidence.
