Customers appreciate our product's excellent build quality, perfect fit, and reasonable price. Many note its robust material and aesthetic appeal, enhancing their engine's appearance. It's effective and practical, with easy installation. However, some suggest checking the back plate bolts prior to installation. Some also indicated the pump enhances clearance issues. Good fit and finish were commonly reported. Users recommend the product for its durability and value, where it stands superior against higher-priced counterparts. Minor inconvenience was with hub holes not properly threaded, easily fixed with a tap.

Well made and excellent price
I ordered this to put on my Chrysler 392 hemi which uses adapters to run this more modern and lighter pump. Speedway has the lowest price and when I got it, it looked perfect. It fits well and has a nice finish. The only problem I had was that the holes in the hub weren't threaded correctly so I had to run a tap through. 5 of repair minutes and it works great now!

I would not purchase this product again, nor recommend it
I ordered and received this water pump and while prepping it to install on my BB Chevy, I found that the port plugs for the heater hose and intake by-pass hose were not removable, they appeared to be glued in place with a clear glue. I returned the water pump to Speedway, which they refunded the product. However, I didn't receive a refund for the shipping cost back to them. I feel since the product was defective that speedway should have cover the return shipping cost as well. Speedway should have a better handle on the quality control of the products that they sell and not waste customers time and resources. I ordered an aluminum water pump from another competitor which worked out perfectly.
