On one of my customs I have 1/4" clearance from the water pump pulley to the fan motor using a Lincoln Mark 8 fan. Yours is probably the same fan.
Check the clearance between the fan and the radiator. Can you make up the 1/2" there? You can't get too close because the plastic shroud will deflect as the fan sucks itself to the radiator. Plan on having at least 1/2".
