SBF 289-351W Water Pump Iron w/Natural Finish

The MR. GASKET SBF 289-351W Water Pump Iron with Natural Finish is a mechanical, high-volume water pump engineered for Small Block Ford engines. This cast iron pump delivers the increased coolant circulation necessary for demanding engine applications, featuring a 5/8-inch pilot bore for reliable hub fitment. Built with durable iron construction and a natural finish, this pump is designed for builders and enthusiasts seeking proven cooling performance in performance, street, and race Small Block Ford builds.

The high-volume design increases coolant flow compared to stock pumps, critical for applications where engine heat output exceeds factory cooling capacity. The 5/8-inch pilot bore ensures secure mounting to the crankshaft snout without slipping or wobble. Iron construction provides superior durability and thermal stability over aluminum alternatives, particularly valuable in supercharged, turbocharged, or carbureted applications where underhood temperatures run elevated. The natural iron finish allows for user customization—powder coating, painting, or polishing—to match your specific engine bay aesthetic and protective requirements.

This pump serves Small Block Ford engine builders, street rod enthusiasts, and race teams requiring upgraded cooling flow. MR. GASKET's reputation in performance cooling components reflects years of application data across various Small Block Ford platforms, from 289 to 351 cubic inch displacement engines. The mechanical (non-serpentine) design makes this pump compatible with classic belt routing systems and vintage engine bay configurations where modern serpentine layouts are not feasible or desired. Weighing 12.03 lbs, it integrates into existing engine packages without significant installation complications.
