Phase III

Although many of the Motion Performance Phase III cars were built around the legendary L-88 427, by the time this 1973 Camaro got the Motion treatment, the Phase III cars were using modified 454s. 500-horse 454s. With a slew full of other options and details, including an available overdrive, the Motion cars were a cut above the other dealer-offered performance fare. Photo: David Newhardt.
