text: 4-door, eight-passenger limousine 1956 (:See also Plymouth Fury) was the last year of this body style before the change in 1957, the only differences offered in 1956 from the previous year were trim packages and the new Dodge D-500. The D-500 was the first Dodge factory high-performance production version as a tribute to the (D-500-1) "Super Stock" model. The only external clues were small crossed checkered flags and "500" lettering on its hood and lower rear deck. It was also available for order from the dealer on Coronet models, including station wagons and two-door sedans. The standard D-500 trim included a  V8 with hemispherical heads (unlike other Dodge V8s (List of Chrysler engines) which used Polyspheric heads), a unique camshaft, valve lifters, pushrods, carburetor, ignition, and pistons. With a compression ratio of 9.25:1, four-barrel Carter WCFB carburetor, and dual-point distribution, peak horsepower was  while torque was a solid . The D-500 also received an upgraded suspension with stiff front coil springs; heavy-duty Oriflow shock absorbers, with the same valving specified for Dodge police cars, were mounted in the springs. Similar units were used in the rear. The overall height of the D-500 was  lower than its standard Dodge counterpart. The D-500 came standard with 15x5.5 inch wheels with 7.60x15 inch tubeless tires. New for safety were safety door locks.
