I made a new 235 water pump into a short shaft pump. I ordered the Ford pulley that Jerry recommends. That all worked out perfectly. But now I can't find a fan that will clear both the crankshaft pulley and the radiator. I bought an Allstar # ALL30104 fan. It just barely hit the crankshaft pulley. When I shimmed it out until it barely cleared the crankshaft pulley, then it hit the radiator. The fan is just too deep from front to back. It would be very easy to find a fan that would fit, if I could find a place where they showed detailed dimensions of them, but I can't. Can any of you point me to a place where I can research this? Or can one of you recommend a fan that will fit?
