Muscle Car Spotlight – 1963 Plymouth/Dodge 426 Max Wedge

By Auto News Log • November 21st, 2009

The 426 RB Wedge (aka Max Wedge) was introduced by Mopar in 1963 as a factory produced “racing only” engine, and was sold through 1964, until it was replaced by the more famous 426 Hemi. According to sales brochures, cars ordered with the Wedge were “not a street machine” but were “designed to be run in supervised, sanctioned drag-strip competition”. The usual combo was to order it in Plymouth’s lightest weight model, the Savoy (pictured here), but it could also be found in the more luxerious Belvedere and Sport Fury models.

The Dodge equivilent was typically found in the Polara, but in both marques, it could be ordered in any model offered (including wagons and convertables). 2,130 Mopar vehicles with this motor installation were produced in 1963. Boasting dual quads and 13.5:1 compression, this power-plant produced 425 hp at 5,600 rpm. Lightweight stockers with this motor flew down the strip in a blinding 12 seconds.
