Side cooling ports allow direct cooling to engine block for high load applications. Beneficial upgrade for engines with aluminum cylinder heads to cool siamese center ports. High-quality short style reinforced aluminum sbc short water pump casting. Precision machined impeller for optimum water flow. Pump provides high flow and high-pressure output for oval track applications. 3/4-inch pump shaft with 3/4-inch fan pilot for sustained high rpm use. Large heavy-duty pump shaft roller bearing to support heavy shaft loads. Extra thick CNC machined fan hub that is press-fit. Pump housing features provision for adjustable cam stop hardware (included) 3/8-inch NPT machined holes on each side of water pump for block cooling. Gaskets and hardware included (actual attaching bolts not included) Keep Your Engine Cool, Lap After Lap Oval track racing, be it asphalt, dirt, or clay, is hard on your equipment. Running wide open lap after lap with everything on “kill” trying to make it to the winner’s circle means your stuff needs to work, and more importantly it needs to last! Nowhere is this more evident than with your race car’s cooling system. Keeping your race car’s temperature gauge in the “green” is not always easy to do, but over the years there have been many sbc cooling tricks to help keep a race car’s engine cool, including retrofitting your small block Fits Chevy for “side cooling.” Side cooling has been around for a long time in motorsports and marine applications and is a great way to help cool an engine that sees continuous high loads. It is especially beneficial in modern racing engines with aluminum cylinder heads. While aluminum sbc heads have many benefits, including larger intake and exhaust ports and thicker decks, all that must be packaged in the constraints of the original iron head’s external dimensions so your intake and exhaust and accessories will still mount properly
