PRW Industries 1444001 Performance Quotient High Flow Aluminum Water Pump Mopar Big Block 361-440 426 Hemi

The PRW Industries 1444001 Performance Quotient High Flow Aluminum Water Pump is engineered for Mopar Big Block 361–440 and 426 Hemi engines. Featuring a 5/8" pilot shaft, an as-cast polished aluminum housing, and a block-to-hub measurement of 3.075", this pump is a direct-fit high-performance upgrade over factory cooling equipment.

Key Features:

• Flows 35 gallons per minute at 4,000 RPM with minimal cavitation and proportionally increased flow rates at 5,000 RPM and above
• Low pressure-injected A356 aluminum alloy pump body for lightweight strength and corrosion resistance
• Precision cast-iron impeller with tight clearances for increased coolant flow, block pressure, and balanced delivery
• Pressure-balanced water passages equalize coolant distribution and minimize internal engine hot spots at any RPM
• As-cast finish with polished housing for a clean, performance appearance
• 5/8" pilot shaft diameter
• Block-to-hub: 3.075"

PRW's high-flow aluminum water pumps significantly improve cooling performance across all street, high-performance, and racing applications. Their superior flow characteristics also make them an excellent choice for trucks, towing, and motorhome use where sustained thermal management is critical.
