From 1962s 300H, the fins were gone, as was the letter series' unique place in the Chrysler lineup; there was now a whole Chrysler 300 Sport Series (which included a four-door hardtop along with a two-door hardtop and convertible), along with the 300H. Externally there was little difference between the 300H and the 300 Sport Series (except for a "300H" badge on the driver's side of the trunk), and many of the 300H's features could be ordered as options on the other models. Under the hood of the 300H the cross ram intake was gone, and there was a return to the inline dual 4-barrel carb setup of the 300E. With a slight power boost and a 300 lb (140 kg) lighter body, the 300H was faster than the 300G, but the loss of exclusivity coupled with high prices made this the slowest-selling letter series year yet, with only 435 coupes and 135 convertibles sold. The regular 300 (non-letter) series used a 383 cu in (6.3 L) B engine.
All 300s for 1962 were demoted to the Chrysler Newport/Dodge 880 122-inch wheelbase body.
