  • 1949-53 Flathead Car Water Pump with Double Narrow Belts
    1949-53 Flathead Car Water Pump with Double Narrow Belts
    SKU-91015595
    x
                

    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.

    • Ceramic seals on sturdy 3/4" shaft
    • High-flow modular impeller reduces cavitation
    • Gasket included
    • Passenger side pump includes threaded boss for heater hose connection
    • Driver side pump does not have heater hose connection

    Fits 1949-1953 Ford cars and 1952-1953 Mercurys with 3/8" belt system. Also fits 1953 F-100 Pickups.

  • Small Block Chevy Cast Alum. Short Pump Double Groove Pulley
    Small Block Chevy Cast Alum. Short Pump Double Groove Pulley
    SKU-91015482
    x
                

    Speedway Cast Aluminum double groove pulleys for Small Block Chevy feature a 20% reduction. Reduction pulleys have a smaller diameter which slows the speed of your fan, water pump, and alternator to reduce drag for more top-end horsepower. Plus, high RPM water pump operation is improved due to reduced fluid cavitation.

    • Machined from lightweight cast aluminum
    • Superior belt retention with extra-deep grooves
    • 20% reduction slows accessories down for less drag
    • Adds top-end horsepower
    • Reduces water pump impeller speed below cavitation threshold
    • Improved high-RPM cooling capabilities
    • 910-15482
      • 6-5/8" O.D.

    Available for Short style pumps ('55-'68). Fits a 5/8" shaft.

    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.

    • Adjustable cam stop
    • Extra-thick fan hub
    • 3/4" inch heavy duty bearing

    Same great quality, now in show polished aluminum!

    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 5/8" shaft, making the assembly exceptionally strong and more efficient.

    Works with 5/8" belts. Includes mount gaskets.

    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.
