Only five 1963 Chevrolet Corvette Grand Sport chassis were built as secret, ultra-lightweight competition cars.
They dropped roughly 1,300 pounds using a tubular steel frame and one-piece fiberglass body.
At Nassau in 1963 the Grand Sports outpaced Shelby’s Cobras, earning the "Snake Eater" nickname.
The 1963 Chevrolet Corvette Grand Sport, one of only five built, is back in the spotlight as a reminder of how far Zora Arkus-Duntov was willing to push America’s sports car in its battle with Carroll Shelby’s Cobra. Conceived as a secret, ultra-lightweight Sting Ray based racer, the Grand Sport was engineered to take on Europe and Shelby on their own terms.
Developed against General Motors’ official ban on factory racing, the Grand Sport swapped the standard Corvette’s heavy frame and body for a tubular steel chassis and one-piece fiberglass shell. The result was a dramatic weight drop from about 3,200 pounds to roughly 1,900 pounds, paired with big V8 power and competition hardware aimed squarely at international endurance events.
