SBC Long Water Pump Iron w/Natural Finish

The SBC Long Water Pump Iron w/Natural Finish from Mr. Gasket is purpose-built for Small Block Chevy engines that demand superior cooling flow without compromising underhood real estate. If you're rebuilding a classic SBC or upgrading a street machine, this mechanical high-volume pump addresses a critical need: maintaining consistent coolant circulation under sustained rpm and heat load. The long-design configuration is engineered for blocks that require extended pump bodies, ensuring proper inlet positioning and unrestricted flow paths that stock units simply cannot deliver.

Cast from durable iron with a natural finish, this pump features a 5/8 inch pilot bore—the standard SBC mounting interface—and is rated for high-volume output to support aggressive cooling demands. The iron construction provides thermal stability and longevity, resisting the thermal cycling stress that plastic or aluminum impellers cannot handle in high-performance applications. The mechanical drive design integrates seamlessly with belt-driven serpentine or traditional V-belt setups, allowing you to maintain proper water distribution across the entire block and cylinder head without electronic complications or dependency on engine management systems.

This pump is ideal for restoration shops, drag racers, and weekend warriors building carbureted or fuel-injected small block combinations where reliability and flow capacity take priority. The long pump profile works best in vehicles with chassis-mounted cooling systems or custom engine bays where standard short-pump designs create fitment conflicts. Installation requires standard SBC mounting hardware and compatibility with your existing belt configuration; verify your block casting and radiator inlet positioning before ordering. Weighing 14.85 lbs, it commands respect as a precision component—not a bolt-on shortcut, but a legitimate upgrade for anyone serious about SBC cooling system performance.
