Did the 41-46 Big bolts only have 6 blade fans, or if any truck was ordered with a shroud have 6 blade fans? With or without heavy duty radiator. I kninda unknowingly put a 4 blade fan with shroud on the 3/4 ton. If I had remembered I had it, I would have used the 6 blade. I have no overheating problems on the 3/4 ton --- 235, 4 blade fan with shroud ---light duty radiator all off a 1.5 ton.

Just curious.
