Jan. 12, 1956 was the birth of the 1956 D-500-1. Versions of the Coronet (the 2 door sedan club coupe and the convertible) were available in full race form. They were also available with optional equipment but this model was the D-500-1, held back until January 12, 1956 to reduce confusion of the two D-500s. So on January 12, 1956 the D-500-1 became official. The fuel system, distributor and cylinder-head configuration were unchanged. What did change was the intake manifold, which supported two Carter WCFB four-barrel carburetors. Additionally, the D-500-1 featured a higher-lift, longer-duration camshaft. These critical changes pushed output to a factory rating of 310hp at 4,800 RPM and 350 foot pounds of torque at 3,200 RPM. Records indicate that just 399 Super D-500 engines were installed in Dodges during the 1957 model year, including this car. Dodge created a series of high performance factory hotrods that not only set records on the salt flats, but on the race tracks all over the world. This was an industry first, and was great for sales. Dodge released a 325 cu in engine for 1957. The engine used a 3.6875 in bore and 3.80 in stroke. The base engine offering was now a polyspheric chambered head referenced as KDS, and a higher performance 325 was offered with hemi heads as the ‘KD-500’. Again there was a low volume offering of a ‘KD-500-1’ with dual four barrel carburetors. All engines now, however, had hydraulic camshafts even though the hemi headed offerings sported dimples in the valve covers for mechanical adjuster clearance.

FROM HEMMINGS MOTOR NEWS ARTICLE: Properly equipped with any of the three available high-output V-8s offered, the "D-500-1" was a real street stunner in its day. Don't believe us? Ask the man who knows a thing or two about performance cars: NASCAR hot shoe and Daytona 500 winner Ryan Newman, the proud owner of the D-500-1 that serves as our subject this month. Along with sleek body lines and a new-for-the-day suspension, the D-500 offers an alternative Mopar muscle car worth considering if you're on the hunt for domestic performance.As potent as the D-500 arrangement was for the time, the Super D-500 was the better performer. Technically called the D-500-1 (not to be confused with the D-501), the basic configuration was identical to the D-500 in that bore and stroke, compression ratio, exhaust system, distributor and cylinder-head configuration were unchanged. What did change was the intake manifold, which supported two Carter WCFB four-barrel carburetors. Additionally, the D-500-1 featured a higher-lift, longer-duration camshaft. These critical changes pushed output to a factory rating of 310hp at 4,800 RPM and 350-lbs.ft. of torque at 3,200 RPM. Records indicate that just 399 Super D-500 engines were installed in Dodges during the 1957 model year.
THIS CORONET WITH THIS HEMI ENGINE IS ALSO CALLED THE SUPER D-500. ONLY 399 OF THESE SUPER D 500-1 ENGINES WERE INSTALLED IN ALL OF THE BODY STYLES OFFERED THAT YEAR. THAT 399 TOTAL INCLUDES 2 DOOR HARDTOP, CONVERTIBLE, AND EVEN STATION WAGON IN ADDITION TO THE TWO DOOR SEDANS THAT WERE BUILT TO RACE IN NASCAR. ALL OF THE K D 500-1's HAD THE BLACK AND GOLD INTERIOR NO MATTER THE EXTERIOR COLORS.
