SBC Water Pump Long

The SBC Water Pump Long from TUFF-STUFF is a mechanical high-volume cooling solution engineered for serious Small Block Chevy builds where OEM capacity falls short. Whether you're running a street engine with upgraded ignition timing, a mild performance package, or a full race application, this long-design pump moves significantly more coolant volume than stock, keeping cylinder head temperatures stable under sustained load. It's the answer for builders who refuse to compromise on thermal management and understand that cooling system upgrades are foundational to reliability and power.

Built from cast iron for durability and thermal conductivity, the SBC Water Pump Long features the extended shaft design that accommodates serpentine belt configurations and aftermarket accessory brackets common in modern Small Block Chevy installations. The high-volume impeller design increases flow rate compared to original equipment, reducing restriction through the cooling jacket and allowing the radiator and thermostat to work more efficiently. The mechanical drive system is reliable and proven, with no electronic controls to fail—just straightforward belt-driven operation tied directly to engine RPM for proportional cooling response.

This pump is ideal for SBC engine swaps, restorations with modern cooling needs, and any application where factory cooling was marginal or inadequate. The long-shaft configuration is essential if you're running a long water pump mounting block or have accessory drives positioned further forward on the engine. Verify your specific Small Block Chevy platform and accessory bracket geometry before installation—shaft length and pulley spacing are critical to proper fitment. Weighing 14.7 lbs and built to withstand high-RPM operation, this pump delivers the dependable, high-capacity cooling that separates amateur builds from engineered installations.
