Details
Original flathead water pumps have always suffered from unreliable bronze bushings and carbon seals. They almost always leaked and even Ford manuals warned mechanics not to tighten fan belts too tight. The excess slack allowed belts to slip and lose contact with the generator and water pump pulleys, causing more cooling and power problems.
Speedway's completely new water pumps feature severe-duty roller and ball bearings, close tolerances and modular impellers to provide maximum flow and reduce cavitation. They also have modern ceramic seals on a heavy duty 3/4" shaft, making the assembly exceptionally strong and more efficient.
Note: This water pump is for 1949-1953 engines in 1948-1952 pickups or 1932-1948 cars.
- Designed for use with 5/8" belt drive system
- Severe-duty roller and ball bearings
- Ceramic seals on sturdy 3/4" shaft
- High-flow modular impeller reduces cavitation

I not sure if I buy this product again
I purchased one roughly 1-1/2 years ago from SM. We ran the engine with water/anti freeze and then the project got put on the back burner due to health issues. The engine sat empty of water/anti freeze. We were prepared to start the engine and this pump was difficult to turn and made a terrible grinding noise. We did not trust the pump so we purchased another one. We purchased the exact same P/N and it came in different than the original. The suction connection was machine with a bead on it to prevent the hose from coming off. VERY NICE! However it is roughly 3/4" shorter than the original. Now the bottom water hose is too short and since we use silicon hose its not cheep to buy more. Important note. Ford Flatheads have two water pumps. We ordered two and ran both of them just as mentioned above. The other pump turns like new and make absolute no noise.

I needed a pair of 8rt wide belt pumps to finish off a customers early style Mercury engine. The Mercury engine was converted to late model 8ba style distributor, running a Mercury 4" crankshaft and wide belt front pulley. Hence then need for the 8RT pumps to align the pulleys.

I bought a pair of these pumps in March 2019 for building an engine using an 8BA block. Time elapsed as build was completed, a '37 Ford Tudor purchased and engine installed. Finally the engine break-in started this year. The DS pump started leaking coolant that became progressively worse. No more than 10 hours of run time. I just bought and received a new pump as a replacement. There appears to be subtle differences in the new pump at the leakage location. In spite of the history and difference I am installing the new pump. I may regret this decision since the probably of another failure is 50/50. There does not appear to be any practical alternative option under Warranty.

I was going to hook them up on my swimming pool but couldn't figure out how to make them work, so I installed them on my Mercury Flathead engine. Haven't started the engine yet so I don't really know if they pump water.
