1759VBP GEN I SBC with Vortec Bypass Port

$182.58

More Power. More Heat!

Flowkooler pump 1759VBP is designed for Gen I SBCs with Vortec heads.  If your setup requires a bypass that is not there we have you covered.  We drill and thread a 3/8" threaded bypass hole to feed the coolant to the rear of the Vortec heads. Images show a brass reducer (not included) to illustrate the location on the passenger side. 

The pump has a 16 blade skip vane impeller that is CNC machined from billet aluminum.  An increased vane count and a reduction in the plate-impeller clearance achieves greater flow rates, higher head pressure and a more efficient flow than other OEM water pumps.  It is then surface coated with a military grade type II Class II anodized finish. 

FlowKooler introduced the first hi flow pumps for the ZZ4 and continues to improve impeller design. Why is increased flow so important to cooling a hot small block 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.
