PQX 1444001 BB WATER PUMP (ALUM HI-VOLUME) $87.60
PRW High Performance Aluminum Water Pump - Mopar 361-440 Big Block & 426 Hemi ® 1958-79, Waterpump (Cartridge Only) Block to Hub 3.075″, As-Cast Finish.
PRW’s high flow aluminum water pumps are engineered to deliver an increased water flow. These “super velocity” pumps significantly improve cooling for all street, high performance and racing applications. With special cast-iron impeller and tight clearances, PRW High Performance Aluminum Water Pumps provide increased coolant flow, block pressure, and balanced delivery. Each pump features low pressure-injected, aluminum alloy pump bodies that are complemented by a precision cast-iron impeller design. This helps minimize engine hot spots at any speed.
Equalized water flow distribution and pressure balanced water passages minimize internal engine hot-spots making these pumps an excellent alternative for not only racers, but also trucks, towing, and motorhome applications. Cruisers and hot rodders will appreciate the improved cooling at low speeds and the availability of polished aluminum water pump bodies for nearly every application.
