Stephen Cox blogs about the sixteenth ’66 Mustang A/Sedan racer built by Shelby,
but never raced.
Originally painted in Ford's familiar Wimbledon White, the car was loaded with go-fast equipment during a lengthy process when it was converted from assembly line stock into a professional racing machine. Like the fifteen cars that preceded it, a K-Code 289/271 small-block powered this Shelby Mustang. In reality, it probably had far more power than that since Shelby's small block Fords routinely registered well beyond 400 horsepower on the dyno.
The car would leap out of corners under acceleration. The Borg-Warner close-ratio four-speed transmission was linked to a 3.89 rear with Detroit Locker differential. The suspension was state of the art for 1966, including lowered front A-arms, front sway bar, with Pitman and idler arms borrowed directly from Shelby's ultra successful GT350R racecars. The factory black interior was mostly stripped, replaced by a racing seat with three-inch safety belts, an 8,000-rpm tachometer and a four-point roll cage.
