1645M 1995-1997 Ford Big Block 460 water pump

$172.38

This pump is the same as the 1645 but we had good feedback telling use enough peopel had to swap out a fan hub to match theirgh pulley (F2UA 8509 and E7TA-8509 used from 1987-1996) that we decided to provide a 8 bolt pattern.  It also has the 2 " lower hose.

If your Big Block Ford is running hot Flowkooler has a solution.  FlowKooler designed a high flow water pump for the 460 block with a CNC machined billet impeller.  It has an increased vane count and a reduced 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 Ford  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!
