Have a 37 Chev with rebuilt 57 235 installed. Have a 6 bladed fan and only have 1/4" clearance between fan and radiator. Would a newer 4 bladed fan have less pitch and then more clearance on the radiator? I think the 6 bladed came off the original 216 in the truck. Have installed the adapter plate to move the water pump to correct height and have short shaft water pump. Any help will be great. Thanks Bill
