One of the rarest Chevrolets ever built, the race-ready

1972 Corvette ZR-1. With just 20 ever produced, it is the rarest small-block Corvette ever built.

1972 is not a year normally associated with top-of-the-line performance cars. Just a few years later, most performance muscle cars would struggle to make even 200 horsepower. In 1970 though, GM introduced a secret production code ZR-1 for Corvettes, and while anyone could order them, few knew about it.

This is the rarest of the small block Corvettes, packing a powerful 370-horsepower LT1 350 engine. A 4-speed “Rockcrusher” heavy duty Muncie transmission came standard and the suspension was set up with stabilizer bars, heavy duty brakes, and special springs and shocks. It was, for all intents and purposes, a race-ready Corvette.

Just 20 ZR-1 Corvettes were built in ’72, 8 in ’71, and 25 in 1970 for a total production run of 53 cars. This makes them enormously rare, though often overlooked in favor of cars like the famous L88. There are just over 16,000 miles on this bad boy, with the original engine, interior, and everything else intact.
