Starting with the 1962 model year, all full-size Plymouths were "downsized", with more compact outside dimensions. Despite the "common sense" that such an idea makes, American car buyers at the time were in the thought mode of "Bigger is Better," and sales of these models suffered. However, the big block V8-engined (426) Belvederes proved to be a terror on the track, and became a desirable drag race car due to its lightweight body.
