Description
The first-generation Ford Mustang was manufactured by Ford from March 1964 until 1973. The introduction of the Mustang created a new class of automobile known as the pony car. The Mustang's styling, with its long hood and short deck, proved wildly popular and inspired a host of competition.
It was initially introduced on April 17, 1964, as a hardtop and convertible with the fastback version put on sale in August 1964. At the time of its introduction, the Mustang, sharing its underpinnings with the Falcon, was slotted into a compact car segment.
The 1966 Mustang debuted with moderate trim changes including a new grille, side ornamentation, wheel covers and gas cap. Ford's new C-4 "cruise-o-matic" three-speed auto transmission became available for the 225 hp V8. The 289 "HiPo" K-code engine was also offered with a c4 transmission, but it had stronger internals and can be identified by the outer casing of the servo which is marked with a 'C'. The long duration solid-lifter camshaft that allowed the high revving 289 to make the horsepower it was known for, was not friendly for a low stall speed automatic torque converter. The "HiPo" could be spotted very easily by the 1-inch-thick (25 mm) vibration damper, (as compared to 1/ 2 inch on the 225-hp version) and the absence of a vacuum advance unit on the dual point distributor. With the valve covers off, there is a large letter "K" stamped between the valve springs, along with screw in studs (vs. a pressed in stud for other 289s) for the adjustable rocker arms. A large number of new paint and interior color options, an AM/ eight-track sound system, and one of the first AM/ FM mono automobile radios were also offered. It also removed the Falcon instrument cluster; the previously optional features, including the round gauges and padded sun visors, became standard equipment. The Mustang would be the best-selling convertible in 1966, with 72, 119 sold, beating the number two Impala by almost 2:1.
