Did you know that the earliest ZR1 Corvettes came into existence long before any of these later iterations?  If not, then take a few minutes to acquaint yourself with one the rarest small-block production Corvettes of all time - the 1970-1972 Corvette ZR1. From 1970 to 1972, Chevrolet offered the ZR1 Special Engine Package, which featured a small-block LT1 engine.
In 1969, Chevrolet changed the perception of Corvette forever by introducing the ultra-powerful ZL-1 Corvette with a 427 CI engine producing 585 horsepower! The 1969 ZL-1 Corvette came equipped with an entirely new big-block engine option that produced more horsepower than any Corvette that had come before it. Any Corvette, when ordered with RPO ZL1, came fitted with an all-aluminum 427 C.I. engine that featured a dry-sump oil system and which weight approximately 100 pounds less.
The Centennial Edition came finished exclusively in a Carbon Flash Metallic finish with satin-black graphics. Special badging graphics signifying Chevrolet’s racing history, including an image of Louis Chevrolet on the B-pillars, were added as accents to the cars finish. The wheels were also finished in satin black. All models also received red brake calipers. The exterior color scheme of the Centennial Edition Corvette is reinforced inside the car.
To commemorate its quarter-century milestone, Callaway Cars collaborated with Chevrolet, arranging a production run of 25 uniquely prepared 2012 Corvette Grand Sport coupes and convertibles. General Motors supplied special parts and procedures on the Bowling Green production line to facilitate final assembly at Callaway factories. Then, the performance and identity components are installed by Callaway. The 25th Anniversary Edition produced 620 bhp and 555 lb-ft of torque.
While not exactly a "collector's edition" Corvette in its own right, it nonetheless has become a uniquely identifiable and collectible Corvette from the fourth-generation era. 1988 marked the 35th anniversary for Corvette, and so it was decided that Chevrolet should commemorate the milestone by introducing an anniversary-edition model. This anniversary car was the first of its kind in a decade, given that Chevrolet opted not to manufacture a Corvette in 1983.
