SMALL BLOCK FORD 289/302/351W ALUMINUM HIGH-FLOW MECHANICAL WATER PUMP

Our high-flow mechanical water pumps provide that extra cooling power your high-performance engine demands. They are lightweight and flow at a rate up to 40% over stock pumps. All mechanical water pumps from TSP are cast from lightweight A356 aluminum and heat-treated to T6 hardness. This not only provides strength, but aluminum works to manage heat far better than cast iron. From top to bottom, TSP's mechanical pumps are designed for greater performance and reliability. They feature an 8-blade, cast aluminum anti-cavitation impeller. Its 5/8" shaft is driven by heavy-duty bearings and seals, and the crank hub is 1/2" thick for added strength. Fits many 65/73 models
