428 Cobra Jet History, by Bill Barr

Bill Barr
My name is Bill Barr, retired from Ford Engine Engineering. Starting in the fall of 1962 I was the Dynamometer Development/Test Engineer for the 1963 Indianapolis pushrod engine and then one of the five engineers in the Indy Engine Group for the 1964 DOHC engine. The 1964 group included a supervisor, a principal engineer, five design engineers, and a Dynamometer Coordinator. The 1965 Indy Engine Group expanded by one engineer. After the 1965 race for which 50 "production" race engines were built and sold (and Jim Clark won the 1965 Indy 500 race), the Indy Race Group was disbanded and personnel were dispersed to other engine engineering projects.
