When I purchased GT350 #3014 it had this fan on it. I was told at the time that it was supposed to have the earlier hi-po fan, so I replaced it. The car is a 4-speed, non-air, non thermactor car. Never had a front end hit, still had the original dated water pump on it. Threre are no markings on it. It looks like a Ford style fan to me. Any opinions or answers?
