Many of the more modern engines have the pump mounted low. This also increases
the head on the intake side of the pump making cavitation less likely.

We're only talking, what, 12 inches of water pressure?  Not much of a head compared
to the 10-16 psi working pressure.  I suspect that the pumps were relocated for
other reasons, perhaps to minimize the trapping of air in the pump (when the
cooling system is serviced)?
