Lost your waterpump bolts? Heres the sizes
For a 1993 F250 460( may be for other years also)
6-4 1/2" bolts
5- 2 1/2 bolts
Bolt size is 5/16-18
when mounting to the block the 2 1/2" bolts go on the highest two holes on the waterpump and are next to each other,then the lowest one on the bottom, also the two holes that are closest to where the pulley bolts on ( they are on opposite sides of each other ), all the rest obviously are the 4 1/2". Be sure to get stainless hardware, these bolts are always a nightmare to remove due to them rusting in the block.
Hope I helped,
