1965-1966
The first GTs were Shelby modified K-Code 289 cubic [4.7 liter] V8 Fastbacks that had their power increased from 271 HP up to 306 HP. Shelby ordered 252 units of 1965 Fastbacks for his conversion into 1966 Shelby GT350. The project itself began in August of 1964 and in September the first Shelby GT350s were born. The public unveil was done on January 27 of 1965. Shelby GT350 also featured Hooly carburetor, Cobra valve covers, special Cobra hi-rise intake manifold, 4-speed manual transmission, side exhaust pipes, Wimbledon white body color with 2 stripes and no back seats, because of SCCA’s requirements [2-door coupes only]. All in all, there were 562 Shelby GT350 street legal and 37 GT360R units built in 1965. The Shelby GT350R were built for races only.
The 1966 production had 2378 GT250s built where 4 of them were special order convertibles for Shelby himself. Some say, there were 6 of these convertibles, but on 4 correct VINs are discovered.
Shelby struck a deal with the Hertz Corporation in 1965 in order to build a special line of 1001 GT350H V8s for “rent a racer” program, which helped Shelby to expose Shelby Mustangs across the country.
