SBC Vette Water Pump 71-82 3/4in Shaft w/Port

The ALLSTAR PERFORMANCE SBC Vette Water Pump 71-82 3/4in Shaft w/Port is a mechanical water pump engineered specifically for Small Block Chevrolet and Corvette engines from 1971 to 1982. This compact, aluminum pump delivers reliable coolant circulation for street, performance, and restoration builds, with a short design that maximizes engine bay clearance and installation flexibility on classic and modified platforms.

The pump features a 3/4-inch pilot shaft diameter, standard for SBC applications, paired with 3/8-inch NPT bypass ports that allow custom coolant routing and thermostat housing integration. The natural aluminum construction resists corrosion while maintaining lightweight performance characteristics. Cam stop hardware is included for secure mounting alignment, eliminating guesswork during installation. The short design reduces overall footprint, making it ideal for tight engine compartments, especially in Corvette platforms where space constraints are common.

This pump is essential for SBC owners undertaking engine rebuilds, restorations, or performance upgrades where original equipment has worn or failed. Whether restoring a 1971–1982 Corvette to original specifications or swapping a classic Small Block into a custom build, the correct water pump ensures consistent coolant flow, prevents overheating, and maintains engine longevity. The bypass port design accommodates both OEM-style cooling systems and aftermarket radiator setups, making it a versatile choice for diverse build configurations.

ALLSTAR PERFORMANCE's commitment to precision manufacturing means this pump meets tight mechanical tolerances, ensuring reliable operation through thousands of miles. For restorers, hot rodders, and performance enthusiasts working with Small Block Chevrolet powerplants, this water pump provides the durability and compatibility needed for dependable cooling system operation across vintage and modified applications.
