Speedway Short Aluminum water pumps flow 35 gallons per minute at 4,000 RPM, with minimal cavitation and proportionally increased flow rates at 5,000 RPM and above. Equalized water flow distribution and pressure-balanced water passages minimize internal engine hot-spots making these pumps an excellent alternative for not only light duty racing, but also marine, trucks, towing, and motorhome applications. Cruisers and hot rodders will appreciate the improved cooling at low speeds.

"Short" style pumps came on all factory small block V8s from 1955 to 1968. However, this pump will fit all S/B Chevys up to 1985.

    Speedway's adjustable water pump is tried, tested and true. It has great flow, superior quality and standard features that are typically only available on water pumps costing twice as much. State-of-the-art aluminum casting and a precision impeller provide equal flow to both cylinder banks. If you're using a cog belt on your race car, this is the pump you want since it's adjustable. The 1/2" mount holes in this pump are larger than normal, allowing it to be moved up or down slightly to help with belt tension.
    • Adjustable mounting holes 
    • High flow and pressure rates 
    • Adjustable cam stop 
    • Extra-thick fan hub 
    • 3/4" inch heavy duty bearing 
    • Pressed-fit and set-screw-retained fan hub 
    • Large-diameter shaft and reinforced housing make it ideal for oval-track applications
