The series started in 1955 (the letter I was skipped) and during this time less than 17,000 were produced. From 1955 through 1957 the Chrysler was the fastest American car, because Chrysler had become the first American manufacturer to develop 300 hp in a production car.

The body styles available were either hardtop or convertible, except 1955,1956, and 1963 when no convertible was available.

The original 300′s are by some people considered to be the first muscle cars, winning a total of 37 NASCAR and AAA stock car events in 1955. But they were not only fast but also large and luxurious. Qualities muscle cars did not typically match.

Of the Chrysler 300L 2,845 cars were produced, 2,405  were 2-door hardtops, and 440 2-door convertibles.

The specifications were as follows: V-8, 413 cid, 4 bbl carb, 360 bhp at 4,800 rpm, 470 ft/lbs at 3,200 rpm, either standard 3-speed auto or optional 4-speed manual.
