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.
Includes a heavy duty bearing and 3/4" shaft and pulley snout; and 1/2" NPT hole on the passenger side (for heater hose) and on the top (for by-pass hose). Thicker (0.100") stamped steel rear plate. Weighs 6 lbs.
This adjustable pump has standard features that are only available on water pumps costing twice as much.
Accents any small block Chevy installation. "Short" style (1955-1968) with 58" shaft and dual bolt pattern hub. 12" NPT ports at top and inlet side for heater hose hook-up. Inlet accepts 1-34" radiator hoses.
1965-1968 Big Block Chevy (BBC) King chrome short leg water pump from OEM castings. Polished to a higher standard and beautifully chrome plated. Built from NEW components.
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" ...

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.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. ...
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.
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.
