I will check a friends garage (his dad was old school engine builder/gear head). There was 3 or 4 - 6 blade fans in the corner. Also has 3 235’s, 10 265’s, 7 power glides, two complete drive trains for 54 or 55 210’s and a ton of other stuff we are sorting through.
The fans just might be the 6 blades from I 6 or from 265/283 v8s
Are there a difference?
