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 $139 at all major retailers. For those wanting a lower cost water pump, see our other listings, but we strongly recommend this unit for those wanting the ultimate in quality and performance.
This water pump is far superior to the low cost units you see available from other sellers. Please do read the info below.
The long style water pump on SBC engines came in use around 1970 and continued in use until the serpentine belt system came along in the late 80s, but many earlier cars may have converted to the long style water pump.
You may see other SBC long style water pumps on that sell for less, but they are not comparable. The cost increase for the aluminum impeller is only part of what makes this water pump a great value. The machine work on the housing is far superior to the low cost units on the market, and the grade of alloy is much better in appearance and quality.
On very rare occasions, we have had complaints of 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.
ALSO AVAILABLE IN POLISHED, CHROME, BLACK SATIN FINISH AND SHORT VERSION.
THIS PUMP HAS THE CORRECT BLOCK TO HUB HEIGHT, 6 15/16".
PLEASE BE AWARE THERE ARE SEVERAL BRANDS OF THIS STYLE WATER PUMP ON THE MARKET. WE CONSIDER THIS TO BE THE MOST RELIABLE WATER PUMP YOU CAN BUY. THIS UNIT IS MUCH BETTER BUILT THAN OTHERS WE HAVE ENCOUNTERED.
IF YOU HAVE A FACTORY SERPENTINE BELT SETUP (CAME OUT AROUND 87 OR SO, RIBBED SINGLE BELT) THIS IS NOT THE WATER PUMP YOU NEED. YOU WILL NEED A REVERSE ROTATION WATER PUMP. SEE OUR OTHER LISTINGS FOR A FULL SELECTION OF WATER PUMPS
How to distinguish a short from a long water pump: 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.
This unit is all aluminum and will flow better than any others we have tested. Continue reading!
Do bear in mind that the alum. 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 little story to prove our point.
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.
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.
This pump is half the weight of a cast iron water pump with no sacrifice in reliability. For those wanting to paint this pump with a contrasting color, it would come out very nice and take painting well. 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 will be 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 at least 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.
BE SURE OF WHAT STYLE WATER PUMP YOU HAVE.
Fast shipping and good quality
