HISTORY
In 1966 the 275 GTB was re-introduced with a four-cam version of the V12 powerplant. The 275 GTB-4 was Ferrari’s first street car to use a quad-cam engine—two camshafts per cylinder bank. With the aid of six Weber carburettors the new engine delivered around 300 horsepower. To cope with the new power, the GTB/4 was given wider tyres and a ZF limited-slip differential. During its production run lasting until 1968, around 320 examples of the 275 GTB/4 were created.
