BBC Chevy 454-496 long style, satin finish. This water pump has a cnc machined aluminum impeller. The rotational weight reduction is considerable. Most all other water pumps have a stamped steel or cast iron impeller. This water pump is considered high end street/strip grade. These water pumps sell for over $150.00 at all major retailers.

*THIS IS NOT THE FINISH YOU WILL RECEIVE. IT WILL BE A SATIN ALUMINUM FINISH. THIS IS A FILE PHOTO *
In the picture above, we are pointing out an area that may interfere with some of the oe steel brackets. The braced aluminum ridge that is pointed out is not on the cast iron oe water pumps. This ridge was designed to strengthen the mounting boss due to the fact that aluminum products of an equal size to cast iron are not as strong. This is an easy fix. You will have to do a slight modification to the bracket in this area. Those using aftermarket March style brackets will not encounter this.
Warranty is valid regardless of street or strip use.
The aluminum impeller in this water pump is designed to reduce rotational mass and dissipate heat at a faster rate, and that's a plus for any car.
Here is a story to prove our point.
We had just installed a 383 stroker engine in a 79 C-3 Corvette and had converted it from mechanical 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 an aluminum water pump, especially one with an aluminum impeller, could reduce operating temps, and it certainly did reduce the engine temp by approx. 10-15 degrees. We now use this line of water pumps exclusively on all of our BBC and SBC turnkey engines we build.
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 don't seem to have heating problems, but for vehicles with modified engines, this is the pump to run, and we proved it.
This pump is half the weight of a cast iron water pump with no sacrifice in reliability. There are no drawbacks to running this type pump, other than cost.
If your pump is still mounted on the engine, the way to tell long from short is that there is nearly no space between the timing cover and back of the water pump IF YOU HAVE A SHORT PUMP. The long pump will have nearly one full inch of space in that area.
PLEASE BE AWARE OF THE MANY INFERIOR WATER PUMPS ON THE MARKET. WE FEEL THIS ONE IS THE BEST AVAILABLE. IN YEARS PAST, WE HAVE SEEN INFERIOR PUMPS THAT BREAK OFF AT THE PUMP SHAFT, CAUSING SEVERE DAMAGE TO THE CAR. OUR PUMPS HAVE HAD NO SUCH FAILURES.
Compare before you buy. We will warranty this pump for LIFE from the date of purchase.
BE SURE OF WHAT STYLE WATER PUMP YOU HAVE.
For those wanting to paint this pump with a contrasting color, it would come out very nice and take painting well. Aluminum water pumps will also dissipate heat better than cast iron. There are no drawbacks to running an aluminum water pump, other than cost.

On rare occasions, we have had complaints of very light water seepage coming from the backplate. We noticed on a few that the amount of sealant used on both sides of the gasket may have been insufficient. We strongly recommend removing the backplate, and coating each side of the gasket with a good quality sealant before installing the water pump on the engine. This is a very simple procedure. The complaints concerning this issue are few and far between, but this is well worth doing as a preventive measure. Besides this minor issue, these water pumps have been extremely reliable for the many years we have been selling them.
BE SURE OF WHAT STYLE WATER PUMP YOU HAVE. THE LONG PUMP IS A BETTER STYLE PUMP TO USE, IF POSSIBLE.
