Corvette Grand Sport at Daytona
A Corvette Grand Sport owned by Bob Adams and driven by Dick Boo. Bob Adams also drove. The car is shown here at the Daytona Speedway around 1971. In early 1962, Corvette Chief Engineer Zora Arkus Duntov began top secret work on a Corvette purpose-built race car to win Sebring and Le Mans and more specifically -- to put an end to the humiliating losses Chevrolet had suffered at the hands of Carrol Shelby and his Cobras. The envisioned Grand Sport would be the ultimate Corvette, a lightweight, tremendously powerful factory built racer. Mounted with a 377cid small block with Weber side-draft carburetors it dynoed at 550hp at 6400rpm and was designed to blow the hoods off Shelby's Cobras. And if the Ferraris and Fort GT 40's were also left in the dust, so much the better. When they learned of Zora's secret program, the Chevrolet boardroom put a stop to the car's construction -- but they couldn't stop the five Grand Sports already built. And neither could the competition. From 1963 to 1967, the cars tore up the racetracks. And even after that, they continued to see duty and put up an excellent showing at races around the country and even overseas. Photo courtesy of Mario Levetto.
