What is a G.T.350R?

Ford introduced the Mustang in 1964 to rave reviews. Not wanting the Mustang’s popularity to be a flash in the pan, Ford decided to the way to ensure longevity was to change the Mustang’s image from a “secretary’s car” to a bona fide performance car. To do that they turned to Carroll Shelby, who was experiencing unparalleled racing success with the Ford 289 in his Cobra.
How did Ford intend to prove to its buyers that the Mustang was a legitimate sports car? By winning races of course. But before that could happen, The Sports Car Club of America (SCCA) had a few requirements for Ford to meet. There had to be at least 100 street and competition versions produced; they had to be two-seaters; and the competition version could have a modified suspension or engine from the street version, but not both. As building a street car with a pumped up race motor didn’t make much sense, Shelby opted to develop the suspension and produce both street and competition versions with the same setup. A street car with competition suspension is much more manageable and desirable versus a street car with a race motor.
And so the Shelby GT-350 Competition Model, or “R Model” was born. Ford couldn’t have dreamed of a better outcome as the R Model dominated B/Production competition, proving to be nearly unbeatable in 1965, winning five out of six regional SCCA championships and the B/Production National Championship.

The R Model is the racing version of the G.T.350 and was only built 36 times in 1965. The price for this master piece was 5995$. Pretty much compared to a regular Mustang which started at about 2500$. Only 1965 Mustang K Code Fastbacks were used and stripped down right at the factory and shipped to Shelby American on Princeton Drive in Venice, CA. The LAX plant was opened several months later.
