Believe it or nuts, the stock fan will work with a 292 in a 1 ton, or at least in my truck. I don't know if the water pump came with a longer or shorter than stock shaft as it came out of a 69 C50 dump truck (as I was told). It did have a spacer behind the fan pulley that made the engine too long and had me making a Rube Goldberg type tensioning system. That spacer put the water pump pulley out to the 3rd groove in the harmonic balancer pulley. By removing the spacer, that moved the pulley back to the first groove (closest to engine) and allowed me to tension the belt with the alternator like it should have been did.
So you learn something every day, and you can teach a dumb dog new tricks. Here is a picture of the space.
Space between pulley and radiator Since I already popped for an electric fan, I'll use that so the truck will go flat out 42 MPH instead of 40 MPH..... :rolleyes:
