Water Pump: 1672<br>Chevy, GMC<br>Big Block Long

After a year of development, Flowkooler water pumps is pleased to announce the introduction of the new 16 blade skip vane CNC machined and military grade anodized aluminum impeller for water pump 1672. With the increased vane count and a reduction in the plate-impeller clearance, we are able to achieve greater flow rates, higher head pressure and a more efficient flow than our longstanding MiraKool design.

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