1955 Chevrolet Corvette EX87 Gallery
Built for outright top speed, this prototype Corvette was built by Zora Duntov. He successfully piloted the car to a two-way average speed of 150 mph in January of 1956 at Daytona. Later two more similar cars were built for the 1956 Daytona Speed Weeks in February.
Duntov modified the car by replacing the windshield with a curved plexiglass windscreen and fitting a fiberglass tonneau cover over the passenger side of the cockpit. Borrowing from recent Jaguar practice, Duntov also fabricated a fiberglass headrest-tailfin for high speed stability. Duntov increased the engine displacement from 283 to 307ci and ordered a special camshaft from Engineering before loading EX87/5951 onto a trailer and heading for GM’s Arizona Desert Proving Ground.
