Plymouth GTX Hemi
Introduced in 1967 as a luxury option in the Belvedere lineup, this model was based on the same platform as the Coronet but was much more luxurious. The GTX was a gentleman’s hot rod with all options, lovely interior and exterior details, and only one optional engine choice – the mighty 426 Hemi. The 440 Magnum was the standard engine, but if you wanted the ultimate Plymouth muscle luxury, you had to go for the Hemi.
