What's in the Box

Info

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.

Item Details

5/8" pilot

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.

really nice piece

July 29, 2015
i changed timing gears and chain, went to a 2 piece front cover and was not going to put my old painted pump back on. this pump is the perfect upgrade and i like the satin look with chrome bolts and polished pulley. a stock chevy pulley will no longer fit but i would not put a painted pulley on this anyway. the 2 piece cover fits fine under this by adding a second set of gaskets when mounting to the block.
Pros:
  • Great price
  • Great quality
Cons:
  • Stock Pulley Will Not Fit
Yes, I recommend this product.

Dont use with the newer plastic T/C

May 22, 2012
The bolt on the bypass side of the t/chain cover hits and holds off the pump on the passenger side. You will need to grind the bolt head as much as possible and shave a little off the back of the pump for it to work. 1996-2001 SBC engine in streetrod so I needed the short pump.
Yes, I recommend this product.

great features for the price.

Same features as other performance brands at THE lowest price. Perfect for a hot street rod. Remember to remove the small plug in the backside for street use. I've had no issues with this water pump.
Yes, I recommend this product.
