"Late 1966 engine casting date, March 10, 1967 machine (build) date, documentation from GM states: information will be available on L-72 in Chevrolet series vehicles after April 3, 1967" And this car in question has a 5E 1967(May 5th week) build date? And this all appeared correct to the people who judged the car? What happened to the 90 day before build date theory? Sounds odd to me.
