Mebbe buying and installing an Edelbrock or Weiand waterpump would avoid:

(1) having to buy any more water pumps
(2) the source of the problems with the existing ignition units and
(3) existing cooling inadequacies.

(Not to say that it wouldn't be neat to convert to the other type of
ignition anyway!!)
