The 1971 Corvette

1971 Black LT-1 Convertible Corvette

The 1971 Chevrolet Corvette is one of the least changed from the previous year. This was the aftermath of the labor problems during '69 and '70. The biggest changes are in the motor to reduce the octane requirements from previous years as mandated by GM. This took higher priority than any cosmetic changes. One thing that was changed was the parking light lenses, most 71's have amber lenses although some early production models have clear. The resin process used to form body parts was also updated to increase quality. This was the last year for the M22 "Rock Crusher" heavy duty transmission. It was named the "Rock Crusher" because of the sounds it made when shifting. Still no black Vettes' this year on the standard order sheet.
