Q & A

What's in the Box

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.

Notes

  1. Not to be used on engines that exceed 5500 rpm. It is better suited to street use than serious racing use. 
  2. There is a plug in the bypass hole of this pump that should be removed for street use.
  3. This pump does not have a set screw to positively retain the hub like a race pump.

Speedway Adjustable Small Block Chevy Aluminum Short Water Pump
SKU-91015582
                        

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

Stewart Components 32203 Stage 3 Small Block Chevy Water Pump, Short
SKU-91015540
                        

These pumps are assembled with 356-T6 heat treated aluminum castings. Precision CNC machined components. The fan hubs are 1/2" thick and machined from billet steel. These pumps are preferred by many top engine builders for higher RPM applications.

These Stage 3 water pumps feature 1/2" thick steel fan hub with set screw for positive positioning and 356-T6 heat treated aluminum casting. The S/B Chevy pump has an extra rigid cam stop with a 3/8" adjusting screw. The extra material adjacent to the block mounting bolts allows drilling and tapping up to 1/2" NPT holes for external cooling lines on S/B Chevy. There is higher flow and pressure for better cooling as well as equal flow to right and left cylinder heads. The 3/4" bearings offer 5 times the strength of standard bearings. Precision impeller installed to exacting tolerances. One year manufacturers warranty.

Red Line 80204 Water Wetter Coolant Additive
SKU-91015709
                        

Red Line Water Wetter Super Coolant additive is a unique wetting agent which reduces coolant temperatures by as much as 20° F. This is a liquid coolant treatment product which is designed to be added to solutions of antifreeze and water to help improve the heat transfer properties of glycol-based antifreeze. This liquid product can be used to provide rust and corrosion protection in plain water for racing engines, which provides much better heat transfer properties than glycol-based antifreeze. Improves the ability of coolant to wet heat transfer surfaces by 50%.

  • Reduces or eliminates bubbles that form on hot metal surfaces to reduce coolant temperatures by up to 20°
  • Superior heat transfer properties compared to glycol-based antifreeze
  • Compatible with new or used antifreeze (including DEX-COOL and long-life versions) to improve the heat transfer of ethylene and propylene glycol systems
  • Improves heat transfer and reduces cylinder head temperature
  • Designed for use with all modern aluminum, cast iron, copper, brass and bronze cooling systems
  • Cleans and lubricates water pump seals
  • Reduces cavitation and complexes with hard water to reduce scaling
  • Does not lower cooling system below the thermostatically-controlled temperature
  • 12 fl. oz. bottle treats 12-20 quarts
