I just put a later model 235 in "54 1/2 ton. According to the block #, it's a '58-'59 eng. The eng fit in the truck perfect. The only problem is the water pump shaft is longer and the radiator won't clear the pump shaft. The water pump is different on a '54 block, so I can't use that pump on the newer engine. Has anyone here run into that, and if so, what is a remedy? Thank you in advance.
