Chassis #: 004
This Chevrolet Grand Sport is powered by a 377 cubic-inch (6.2 liters) V8 producing 485 horsepower at 6000 RPM. It rides on a 98-inch wheelbase and weighs 2150 pounds.
Intended as a series of 125, the 'Lightweight,' at a thousand pounds less than the production Sting Ray, was supposed to counter Carroll Shelby's brand new Cobras in GT World Championship races. But the Grand Sport program died almost the day it was born, killed by GM's refusal to lift its ban on racing. When the ax fell at year-end 1962, only five cars existed at Chevrolet's Research Center. Two were quickly 'sold' to private teams. The orphaned cars could not be homologated as production GTs like the Cobras, and consequently had to race in C Modified, a class for which they were never intended. During the 1963 Nassau Speed Week, however, vindication came when the Grand Sports were allowed to compete directly wîth the Cobras. Entered by 'owner' John Mecom and backed by a team of Chevrolet engineers who had conveniently chosen Nassau for a one week 'vacation,' and refitted wîth 377-cid aluminum engines, the cars simply demolished their Cobra rivals. Drivers Roger Penske, Jim Hall, Dick Thompson, John Cannon and Augie Pabst joined the Chevrolet engineers in smirking at their victory over the hated Cobras.Source - Historical notes courtesy of The Collier Collection
