Something to keep in mind if you're reusing the current engine block -
if, due to bad bearings, the water pump is spinning at an angle, the
impeller will rub against and wear the block, increasing the tolerance
and decreasing the efficiency of the new pump if allowed to go on for
long.

Not important if you're junking the case, but . . .

or replace the pump in the current
