Water Pump SBC Short 71-82 Corvette Adj

The Water Pump SBC Short 71-82 Corvette Adj from STEWART is a Stage 3 Severe Duty mechanical water pump engineered for small block Chevy engines in classic Corvettes and high-performance street/race applications. This adjustable pump delivers reliable coolant circulation in demanding conditions where factory cooling systems fall short, making it essential for builders pursuing consistent engine temperatures during sustained driving or competition use.

Built from aluminum in a natural finish, this short-design pump features adjustable timing capability via a 3/4-inch pilot bore, allowing tuners to optimize coolant flow characteristics for their specific engine setup and cooling needs. The Stage 3 Severe Duty construction means thicker castings, precision-balanced internals, and high-flow impeller design—critical upgrades when stock pumps cannot maintain safe operating temperatures under boost, prolonged acceleration, or high-RPM operation. The compact short design saves engine bay space while maintaining full flow capacity.

Corvette enthusiasts, street rod builders, and track-focused small block Chevy owners benefit most from this pump's reliability and tuning flexibility. Installation suits 1971–1982 Corvettes and compatible small block Chevy platforms running aggressive cam profiles, nitrous, or elevated RPM ranges. The adjustable pilot allows fine-tuning of flow timing to match your ignition curve and cooling circuit layout, making it ideal for both carbureted and fuel-injected applications requiring precision temperature management. Each unit ships ready for mechanical drive installation.
