SBC Water Pump - Short- 3/4in Shaft- R/R

The Edelbrock 8815 SBC Water Pump is a mechanical water pump engineered for small-block Chevy engines requiring reverse-rotation capability in high-performance and custom engine configurations. This short-design aluminum pump features a 3/4-inch pilot shaft and delivers reliable coolant circulation in applications where standard forward-rotation pumps cannot be used.

The reverse-rotation design is critical for engine builders using serpentine belt systems, custom accessory drives, or engine bay layouts where the crankshaft rotation runs counter to conventional setups. The short-profile housing minimizes clearance conflicts in tight engine compartments while the 3/4-inch shaft diameter ensures compatibility with standard small-block Chevy mounting provisions. Natural aluminum construction provides a lightweight, corrosion-resistant option for both street and competition builds where weight savings contribute to overall performance gains.

Buyers restoring or modifying small-block Chevy engines—whether for street cars, track vehicles, or engine swaps—rely on purpose-built reverse-rotation pumps to ensure proper coolant flow without modifications to the drivetrain or ignition timing components. The Edelbrock 8815 eliminates the need for custom adapters or workarounds in applications where factory pump orientation creates interference or functional conflicts.

This pump integrates into the Victor Series engine platform, supporting the precision cooling requirements of high-output small-block combinations. Proper coolant circulation is non-negotiable in performance engine builds, and the reverse-rotation configuration ensures thermal management without requiring expensive or time-consuming engine modifications.
