Z/28



The Z/28 is so named from its original RPO code (RPO28). Z-trims have been used by Chevrolet to denote other specialty performance products that SS doesn't cover.

Origins
The intention was to produce a race-ready vehicle from the factory. The 1967 Z/28 featured a 327 engine with a 283 crankshaft. This made the Z/28 a 302ci engine, fitting under the 305ci limit set by the SCCA.

Entering the Mainstream
In 1977, the Z/28 returned to the lineup due to popular demand. The Z/28, eventually Z28, would become the mainstream performance Camaro. The Camaro SS was dropped. In the 4th generation, the Camaro Z28 served as the main performance trim with the Camaro SS serving as the premium performance trim.

Return to Tradition
In the 5th generation, the Z/28 entered the market late in production as a track-oriented trim with the Camaro SS serving as the main performance trim. It serves as a stripped model with less luxury features, unlike the Camaro SS, and more performance.
