1967 Plymouth R023 GTX — 55 Produced


The GTX R023 was designed for racing. Plymouth did away with the GTX’s hubcaps, radio, heater, body insulations and carpet in order to save as much weight as possible. The R023 was over 500 pounds lighter than a regular GTX even after it was fitted with a 426 cubic inch Hemi engine. The car was also designed with larger hood scoops in order to increase airflow to the massive engine block. It was capable of doing 0 to 60 in 4.8 seconds.
