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. Quality short style reinforced aluminum sbc short water pump casting. Precision machined curved impeller for optimum water flow. Pump provides high flow and high pressure output for oval track applications. 3/4-inch pump shaft with 5/8-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 and retained by a snap ring. 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 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. This leaves the aluminum sbc head with smaller coolant passages, creating cooling issues in these applications. By pumping the water just cooled by the radiator directly into each side of the engine block it helps keep things cooler, especially the siamese center ports. Ready For Your Side Cooling Upgrade Starting with our popular high flow/high pressure short sbc aluminum water pump assembly, we machine the reinforced aluminum casting for 3/8-inch NPT fittings on each side of the pump to provide water outlet connections for plumbing to your engine block’s water jacket to aid in cooling the siamese center exhaust ports/valves of the sbc heads. These ports machined into our sbc short water pump allow the installation of 3/8-inch NPT fittings of your choice (hose barb, AN 37 degree, etc.) and as such we do not include any port fittings due to the wide variations in line choices, line routing, and more. The precision machined impeller in our sbc aluminum water pump guarantees sufficient water flow for side cooling conversions while still being used as a traditional sbc short water pump that pushes coolant into the front of the block. The heavy duty 3/4-inch pump shaft, supported by a large roller bearing, ensures a long trouble-free service life, lap after lap and features a 5/8-inch fan pilot. The CNC-machined fan hub measures .3655-inch thick and ensures your water pump pulley runs straight and true and can support the loads a dual V-belt racing setup imparts on a water pump. Installs Just Like a Standard Small Block Chevy Water Pump Replacing a small block Chevy’s water pump is often a quite simple affair, especially when there aren’t any accessories in the way. Chevy really makes it easy with just four bolts. The Speedway Motors version attaches the same way (if you need new mounting bolts we have those as well). We have also included an adjustable cam stop boss with adjustment stud and lock nut
