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.
Moroso first pioneered the aluminum water pump for racing over 15 years ago. Over the years, continual improvements have resulted in providing the best cooling system components available for competition use.
NOTE: This pump is designed for street use and is not to be run on a motor which exceeds 5,500 RPM.
1955-1968 Small Block Chevy (SBC) King chrome short leg water pump from OEM castings. Polished to a higher standard and beautifully chrome plated. Built from NEW components.
Our B/B Chevy water pumps feature a CNC machined iron impeller, ribbed aluminum housing, and a heavy duty bearing assembly. These mechanical pumps flow up to 35% more coolant than stock pumps. Plus, thesealuminum pumps weigh less than half than the stock pump and require less power to operate.
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.
