Shelby Mustang

The Shelby Mustang is a high performance variant of the Ford Mustang built from 1965 through 1970. Following the introduction of the Fifth-generation Ford Mustang the Shelby nameplate was revived in 2007 for new high performance versions of the Mustang.[1]

These cars are properly not called "Cobras", which was the Ford-powered AC-based two-seat sports car also produced by Carroll Shelby during the same period. The confusion arises from the optional "Cobra" valve covers on many GT350s, part of a marketing tie-in by Shelby. All 1965-66 cars featured the "K" code 271 hp 289, modified to produce 306 hp. 1965-66 GT350s were delivered from Ford's San Jose assembly plant as "bodies in white" for modification by Carroll Shelby's operation, originally in Venice Beach and later at Los Angeles International Airport.

All but one 1965 GT350s were painted Wimbledon White with Guardsman Blue rocker stripes. The one exception was blue with white stripes. Contrary to popular belief, very few GT350s were delivered with the optional "Le Mans" hood, roof, and trunk stripes, an option which was usually installed by the dealer. Today it's difficult to find a GT350 not so equipped. 1965 cars had the battery relocated to the trunk, featured overrider traction bars, relocated A-arms, and other modifications.

1966 saw the introduction of non-white colors — including blue, red, green and black. Other changes include special quarter-panel windows replacing the factory extractor vents, functional brake scoops on each side and optional automatic transmissions, as well as the addition of an optional Paxton supercharger. The battery was no longer relocated to the trunk for 1966, and the over-rider traction bars were discontinued. A fold-down rear seat was now standard. Where early 1965 cars had black engine blocks, 1966 and later cars had the 289 engine painted blue. The first 252 GT-350s for 1966 began as 1965 Mustang K-Code Fastbacks. Often these first 252 1966 GT-350s are referred to as "carry-over" cars, but this is not the case. These 252 1965 Model Mustangs were specifically ordered by Shelby American for conversion into 1966 GT-350 Mustangs. They were not "left over" from the 1965 production, at all. They had the 1965 Ford Mustang Bodies and 1965 Ford Mustang serial numbers under their Shelby serial numbers. They mostly had 1965 features including standard Koni shock absorbers and engines painted black. Blue engines did not appear in 1966 until after these first 252 GT-350s were produced. 1966 production was 1373 fastbacks, including two prototypes and four drag cars, and 252 early production models with Ford Mustang 1965 bodies. 1001 Hertz fastbacks were produced, including two prototypes. Four convertibles were also produced, for a total of 2378 units for 1966. A small number (how many remains unclear) of '66s were fitted with Paxton superchargers, but not the No-Spin limited slip differential, with an option price of US$670; the engine was rated at 440 hp (330 kW).[2]
