How to distinguish a short from a long water pump:
If your pump is still mounted on the engine, the way to tell long from short will be that SHORT PUMPS have nearly no space between the timing cover and back of the water pump. The long pump will have at least one full inch of space in that area. If you can place your fingers between the timing cover and back side of the water pump, then you have a long style water pump. Short water pumps are right up against the timing cover.

Aluminum Water Pumps
Aluminum water pumps provide many benefits over a typical cast pumps. They are typically half the weight and very reliable. The aluminum surface accepts paint well.
Aluminum vs Steel Impellers
Our water pumps feature aluminum impellers to reduce rotational mass and dissipate heat quicker. That's a plus for any engine. Most aluminum water pumps have stamped steel impellers or at best machined iron impellers, and claim to be high volume. We have used other brands and styles of water pumps on stock engines that are not modified, and we don't seem to have heating problems, but for vehicles with modified engines, this is the pump to run, and we proved it on our dynos.
We had just installed a 383 stroker engine in a 79 C-3 Corvette and had converted this to electric fans and could not stop the car from running hotter than we were comfortable with. The temp would soar to 235 in as little as ten minutes. We then replaced the OEM cast iron water pump with one of our aluminum water pumps with the aluminum impeller. We knew that aluminum water pumps, especially those with an aluminum impeller, could reduce operating temps, and it certainly did reduce the engine temp by approx. 15 degrees. We now use this water pump exclusively on all of our SBC turn key engines we build.
If you don't have quality mounting hardware in good condition, be sure to check out our catalog or call us at 423-722-5152 and we'll help you get what you need. Our engines are assembled with RTV Silicone on the gasket and threads to ensure a good seal. Stainless steel hardware will prevent corrosion on bolts that enter waterpassages.
