I thought I read that there was a water pump change in 37 and if it did happen did the water pump get longer or shorter,getting the new 235 ready to drop in my 37 and found what I think is a original fan which hits the balancer. There is only 1/4 inch between the fan and radiator with the present engine that has a 49 to 54 fan and I am trying to get a little more distance,found a fan off a 46 to 48 that has notches to clear the balancer but it has thicker blades that might put me back where it is now. Both engines are 55 to 62 235s with 54 water pumps with the adapter.
