1967 Plymouth GTX - Gen III Hemi Swap

In 1967, Plymouth introduced the GTX as the trim level for their mid-size Belvedere. Positioned as the "gentlemen's hot rod," the GTX came standard with the Commando 440 cubic inch big block with the 426 cubic inch Hemi as the only optional engine. Today, there is one more option thanks to our Gen III Hemi swap systems.
