Chrome Steel Crankshaft Pulley 3Groove Long WP

The Chrome Steel Crankshaft Pulley 3-Groove Long Water Pump from Racing Power Co-Packaged is a precision-engineered pulley designed for small block Chevy engines requiring reliable belt drive integration. This 7.8-inch diameter pulley features three V-belt grooves and a chrome-plated steel construction, delivering both durability and the polished appearance critical to engine bay aesthetics in performance and restoration applications.

The long water pump configuration ensures proper alignment and spacing for small block Chevy engines equipped with extended water pump housings, a common requirement in both original and modified engine builds. Chrome plating over steel provides corrosion resistance while maintaining excellent grip for accessory belt tension, critical for maintaining proper alternator output, water pump cooling capacity, and air conditioning function. The three-groove design is the industry standard for small block applications, accommodating multiple belts or a single serpentine belt depending on the engine's accessory configuration.

This pulley is essential for engine builders, restoration specialists, and small block Chevy enthusiasts who require OEM-style or modern serpentine belt compatibility. Whether rebuilding a classic street engine, restoring a vintage vehicle, or upgrading cooling and charging systems in a performance application, this Racing Power Co-Packaged pulley delivers the precision fitment and finish quality expected in professional engine work.

Small block Chevy crankshaft pulleys are available in various configurations—short water pump, long water pump, and different groove counts. The long water pump variant with three grooves represents the most versatile specification for both vintage restorations and modern engine swaps, ensuring compatibility across a wide range of small block applications from the 265 through the 400 cubic inch platforms.

Sold as a single unit, this pulley is a critical rotating component in any small block Chevy engine assembly and should be paired with appropriate belts and tensioners rated for the specific engine displacement and accessory load.
