I can recommend the Edelbrock aluminum water pump. It has oversized ball bearings (instead of a brass bushings) and is a high output design. I've had mine for 5 years now with no problems what-so-ever. Before that I had an auto supply cast iron pump and then a FlowCooler aluminum pump (made offshore I later found out). Both had brass bushings instead of ball bearings and both leaked within a year or two. I think it cost me $150 five years ago from Summit for the Edelbrock.
