The new 1970-72 Judging Manual on page 155 states 350's w/o air have a 5 blade fan without a part # or date and air 350 units have a 7 blade fan stamped with both part and date data. The 1970 Assembly Manual UPC C 60 / C1 illustration depicts a 5 blade fan for 350 engines w/air.
The Motorbooks Workshop Corvette 1968-1982 Restoration Guide by Richard Prince on page 101 states "A minority of air-conditioned cars have a 5 blade fan instead of the more commonly seen 7 blade fans."
The 1970 I've owned since 1972 has factory air and a 5 blade fan as described above. The body build code is C 23. To my knowledge the 5 blade fan is original to the car.
To validate (or refute) there are other air 350's with factory installed 5 blade fans, please respond to this post indicating what fan your air 350 is equipped with. Thanks...Clark
