BBC 3 Goove Crank Pulley Long W/P Satin

The BBC 3 Groove Crank Pulley Long W/P Satin from Racing Power Co-Packaged is a precision crankshaft pulley engineered for Big Block Chevy applications requiring long water pump configuration. This aluminum pulley features a three-groove V-belt design with 7.8-inch diameter and satin finish, delivering the OEM-style functionality modern engine builders and restoration specialists demand when rebuilding classic Big Block power plants.

The 3-groove profile matches the serpentine belt arrangement on long water pump Big Block Chevy engines, ensuring proper belt tension and accessory drive synchronization across alternator, power steering pump, and cooling system components. Aluminum construction keeps rotating mass minimal while the satin finish resists oxidation and maintains a factory-correct appearance. The pulley's 7.8-inch diameter is optimized for the belt ratios and RPM range typical of Big Block Chevy street and performance builds, with proper engagement geometry to prevent slippage during sustained acceleration or high-load operation.

This pulley serves engine builders, classic car restorers, and street performance enthusiasts working with Big Block Chevy power plants (BBC 427, 454, or equivalent displacement). Long water pump configurations are standard on many vintage BBC installations and specific LS-era engine conversions, making pulley compatibility critical to avoid accessory belt misalignment and premature wear. The Racing Power Co-Packaged offering provides OEM-specification replacement and upgrade applications at a practical price point.
