The fastest, most powerful American production model for 1955 and the car that shook the car scene was the mighty Chrysler C-300. This was the start of a 10-year production run of Chrysler’s famous “Letter cars.” It was a series of exclusive, fast, and expensive coupes and convertibles with maximum power, comfort, and luxury (via Concept Carz).
The first car in that glorious lineup was the ’55 C-300. The car got its name from the 331 V8 Hemi engine they equipped with 8.5:1 compression. It also got a race camshaft and twin four-barrel carburetors to produce 300 HP, which was a magical figure for the mid-1950s.
