1974 1996-2014 Small Block Long CW or CCW 262 305 350 Vortec water pump

SBC running hot? Flowkooler designed a high flow water pump with a CNC machined billet impeller with an increased vane count and 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.  Why is increased flow so important to cooling a hot Vortec 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!
