The AC Cobra, sold as the Shelby Cobra in the United States of America, is an Anglo-American sports car with a Ford V8 engine, produced intermittently in both the UK and United States of America since 1962.
Like many British manufacturers, AC Cars had been using the Bristol straight-6 engine in its small-volume production, including its AC Ace two-seater roadster. This had a hand-built body with a steel tube frame, and aluminium body panels that were made using English wheeling machines.
The engine was a pre-World War II design by BMW which by the 1960s was considered dated. Bristol decided in 1961 to cease production of its engine and instead to use Chrysler 313 cu in (5.1 L) V8 engines. AC started using the 2.6 litre Ford Zephyr engine in its cars. In September 1961, American automotive designer Carroll Shelby wrote to AC asking if they would build him a car modified to accept a V8 engine.
AC agreed, provided a suitable engine could be found. Shelby went to Chevrolet to see if they would provide him with engines, but not wanting to add competition to the Corvette they said no. However, Ford wanted a car that could compete with the Corvette and they happened to have a brand new engine which could be used in this endeavor: Ford’s 260 in³ HiPo (4.2 L) engine – a new lightweight, thin-wall cast small-block V8 tuned for high performance. Ford provided Shelby with two engines.
In January 1962 mechanics at AC Cars in Thames Ditton, Surrey fitted the prototype chassis CSX2000 with a 260 ci Ford V8 borrowed from Ford in the UK; the 221 ci was never sent. However, early engineering drawings were titled “AC Ace 3.6”. After testing and modification, the engine and transmission were removed and the chassis was air-freighted to Shelby in Los Angeles on 2 February 1962. His team fitted it with an engine and transmission in less than eight hours at Dean Moon’s shop in Santa Fe Springs, California, and began road-testing.
The new car was designed in cooperation with Ford in Detroit. A new chassis was built using 4 in (102 mm) main chassis tubes (up from 3 in (76 mm)) and coil spring suspension all around. The new car also had wide fenders and a larger radiator opening.
It was powered by the “side oiler” Ford 427 engine (7.0 L) rated at 425 bhp (317 kW), which provided a top speed of 164 mph (262 km/h) in the standard model and 485 bhp (362 kW) with a top speed of 185 mph (298 km/h) in the competition model.
Cobra Mark III production began on 1 January 1965; two prototypes had been sent to the United States in October 1964. Cars were sent to the US as unpainted rolling chassis, and they were finished in Shelby’s workshop.
Although an impressive automobile, the car was a financial failure and did not sell well. In fact to save cost, most AC Cobra 427s were actually fitted with Ford’s 428 cubic inches (7.01 L) engine, a long stroke, smaller bore, lower cost engine, intended for road use rather than racing.
It seems that a total of 300 Mark III cars were sent to Shelby in the USA during the years 1965 and 1966, including the competition version. 27 small block narrow fender versions, which were referred to as the AC 289, were sold in Europe.
Unfortunately, The MK III missed homologation for the 1965 racing season and was not raced by the Shelby team. However, it was raced successfully by many privateers and went on to win races all the way into the 1970s. The remaining 31 unsold examples were detuned and fitted with wind screens for street use. Called S/C for semi-competition, an original example can currently sell for 1.5 million USD, making it one of the most valuable Cobra variants.
Shelby wanted the AC Cobras to be “Corvette-Beaters” and at nearly 500 lb (227 kg) less than the Chevrolet Corvette, the lightweight roadster accomplished that goal at Riverside International Raceway on 2 February 1963.
Driver Dave MacDonald piloted CSX2026 past a field of Corvettes, Jaguars, Porsches, and Maseratis and recorded the Cobra’s historic first-ever victory. Later, Shelby offered a drag package, known as the Dragonsnake, which won several NHRA National events with Bruce Larson or Ed Hedrick at the wheel of CSX2093.
Only five Dragonsnake Cobras were produced by the factory, with three others (such as CSX2093) prepared by customers using the drag package.
