SBC Water Pump Long Black Cast

The SBC Water Pump Long Black Cast from TUFF-STUFF is a high-volume mechanical coolant circulation system engineered for small block Chevy engines requiring maximum cooling capacity under sustained load. Built for street performance, track duty, and modified engine applications, this long-design water pump delivers superior flow rates compared to stock units, making it essential for engine builders, hot rodders, and mechanics upgrading cooling systems on 350, 327, and other SBC platforms. Whether you're running increased boost, higher RPM limits, or tighter engine bays, this pump maintains consistent coolant velocity to prevent hot spots and thermal instability.

This mechanical-drive water pump features cast-iron construction with a durable black powder-coat finish, resisting corrosion and heat degradation in harsh underhood environments. The long-design configuration accommodates extended serpentine belt routing common in modern SBC installations and engine conversions, while the high-volume impeller geometry accelerates coolant flow through the block and cylinder head passages. Cast-iron construction provides thermal stability and durability that outlasts aluminum alternatives under extreme conditions, and the robust bearing and seal design handles continuous high-RPM operation without premature wear.

Ideal for engine builders, restoration specialists, and performance shops, the SBC Water Pump Long Black Cast integrates seamlessly into stock and custom cooling circuits for small block Chevrolet engines. Installation requires standard small block Chevy engine bay clearance and compatible belt routing; always verify fitment with your specific intake manifold, alternator, and accessory drive configuration. At 14.9 lbs with compact 9.6 x 8.9 x 13.1 inch dimensions, this pump balances mass-flow performance with practical installation geometry, making it the go-to choice for builders prioritizing reliability and cooling efficiency in modified SBC applications.
