The 1967 model year was the first major redesign for the classic Mustang. The increase in size allowed the installation of a big-block V8 engine. The overall exterior, interior and cargo space was increased for an all-new look. Exterior trim changes included concave taillights, custom side ornamentation, square size view mirrors and yearly gas cap changes.
With the introduction of an all-new Mustang, the 289 cubic-inch V8 option was carried over from 1964-1966. A 335 horsepower big-block 390 cubic-inch V8 was added to the engine line-up for top performance variations. When paired with a 4-speed top loader manual transmission the 1967 Mustang recorded quarter mile times of approximately 13 seconds and trap speeds of over 105 mph.
Changes for the 1968 Mustang increased safety with a two-spoke energy absorbing steering wheel, 3-point seat belts, along with front and rear side markers on the exterior. The 289 cubic-inch V8 was discontinued and the famous 302 cubic-inch Windsor v8 came standard.
Many specialized models were available for the 1967-68 Mustang which included the California Special, and a unique green 1968 Ford Mustang GT Fastback that reached iconic status after it starred in the movie Bullitt.
