UNFORTUNATELY THE FOUNDRIES THAT SUPPLY US THIS CASTING HAVE BEEN UNABLE TO CONSISTENTLY PROVIDE THE CORRECT CASTING.  IF YOU PURCHASE THE 1779 SINGLE GROOVE PUMP FOR THIS APPLICATION YOU MAY EXPERIENCE BELT INTERFERENCE.  WE ARE REMOVING THIS ITEM FROM SALE UNTIL WE CAN FIND A RELIABLE SOURCE.

Flowkooler high flow pump 1778 fits the Cadillac 472 and 500ci blocks. It has a CNC machined billet impeller designed with an increased vane count and a reduced impeller clearance to achieve greater flow rates, higher block pressure. A Type II Class II military grade anodize surface coating protects against corrosive fluids.

We developed this hi flow pump because Cadillacs are big and heavy and tend to get hot as they age.  It has been proven time and time again that reducing the cycle time between the heat source and the heat sink drops engine temperatures for slow speed cruising and stop and go traffic.

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