1773 1971-1996 Buick Chevy GM Olds Pontiac 305 307 350 383 400 6-7/8" tall water pump

$129.00

Is your small block running hot?  Flowkooler designed a high flow water pump with a CNC machined billet impeller with 16 vanes, integrated shrouding and a reduced casting-to-impeller vane clearance.  It achieves greater flow rates, higher head pressure and a more efficient flow. The impeller color is due to Type II Class II military grade surface coating which protects against corrosive fluids. 

FlowKooler introduced the first hi flow pumps and continues to improve impeller design. Why is increased flow so important to cooling a hot SBC engine? Because it has been proven time and time again that reducing the cycle time between the heat source and the heat sink creates more opportunities to shed heat and drop engine temperatures.

From 0-3,300 RPM…Nothing Beats a FlowKooler!
