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. This pump does not have a set screw to positively retain the hub like a race pump.

perfect for old Vette

March 14, 2016
Used this on my 59 Vette. the Vette uses the front motor mount that goes under & over the water pump. most pumps have a boss cast on top for alternator mounting that will not clear the mount. this water pump does not have that boss, so it fit without modification. would have given five stars, but i just put it on, dont know if it will last. If you dont need the mounting boss, this water pump looks cleaner without it.
Yes, I recommend this product.

Packaging is not good

October 21, 2015
This pump looks pretty good. I have not finished my build yet so I cannot say how well it operates. I will say that the packaging from the manufacturer is terrible and leaves the pump very unprotected in the box. I had to send the forst one back as it incurred damage during shipping due to the lousy packaging. If you get one be sure to inspect very carefully!
Yes, I recommend this product.

This pump has a 5/8" shaft diameter. Sorry, we do not currently offer a pump with a 1/2" shaft.
