The Story of the C3, C4, C6, and C7 ZR-1/ZR1 Corvette: Part 1 of 4
The 1970-1/2 – 1972 ZR-1: There have been three distinctive “ZR-1 / ZR1” Corvettes since 1970. The first ZR-1 was actually the last of Duntov’s “Racer Kit” option packages, designed to provide a Corvette customer with the basics needed to go SCCA racing. Offered from 1970-1/2 to 1972, the RPO ZR-1 (and RPO ZR-2) were strictly “under-the-skin” hardware packages. There were no special badges, scoops, vents, limps, bumps, or budges. From the outside, the ZR-1 looked like any other LT-1 or 454 (as with the ZR-2) Corvette. These unique cars were not “marketed” in any way at all. You had to know about them to seek one out, and most of them, likely never saw street use.
