Finally in 1971, both the ZR1 and ZR2 packages were offered side by side as initially intended. The solid lifter, 350 cubic-inch LT-1 found under the hood of the ZR1 featured a ‘178’ high-performance camshaft and a 780 CFM Holley four-barrel carburetor, which resided atop a specialized aluminum intake. The LT-1 featured a reduced compression ratio of 9.0:1 for the 1971 production year, relative to 11.0:1 specified the year prior.

1989 Corvette DR-1 Concept

There were several successful attempts to build a convertible ZR-1, most of them by private people. The DR-1 was a GM prototype to test the structural integrity of the ZR-1 chassis when it would be topless. The car was built by American Sunroof Corporation (ASC) for Don Runkle, who was the vice-president of Advanced Engineering Staff, which explains the “DR-1” designation. It was a standard convertible transformed to ZR-1 specs.

Anniversary Edition

2003 Corvette 50th Anniversary Edition

Another decade – another milestone anniversary edition Corvette. However, the 2003 model year was especially significant as it marked the 50th year of the Corvette’s production at Chevrolet.  To commemorate a half-century of manufacturing, every Corvette built in 2003 was adorned with special “50th Anniversary” badging – a unique “50” badge on each of the front fenders above the bodyside coves, and a special crossed flags badge that included “50 Anniversary” badging.

Chevrolet Corvette ZR-1 Spyder prototype, 1991, by ASC. An experimental styling prototype ordered by Don Runkle, Chevrolet’s chief engineer, to see how far the ZR-1 might be pushed in convertible form.

The black example in the National Corvette Museum was originally painted Sebring Silver with a Neutrino Yellow interior.
