By 1968, the Ford Mustang had already gained iconic status, being a popular choice among U.S. sports car enthusiasts due to its lightweight design, powerful drivetrains, and aggressive looks. The arrival of the Shelby GT350 in 1965 gave Ford even more credence on the performance market. The Shelbys became increasingly powerful over the years, but that didn’t stop Ford and Carroll Shelby to develop larger and more potent mills. In April 1968, a brand-new version of the 428-cubic-inch (7.0-liter) Police Interceptor V8 engine, with improved breathing heads and larger exhaust manifolds, was launched. Dropped into the range-topping Shelby GT500, the new engine gave birth to the Cobra GT500 KR.
