Designed for Big Block Chevy applications. This March Performance pulley kit replaces the factory crank, water pump and alternator pulleys with a matched set CNC-machined from 6061-T6 billet aluminum. Matched diameters keep the accessory drive working together, and the billet construction is lighter and stronger than stamped steel or cast pulleys. It is a straightforward bolt-on upgrade that also dresses up the front of the engine.
This part number is configured as follows: Finish: Black. Application: Chevy Big Block 7.287" Standard Rotation Long Water Pump. Kit includes: 7331 Double 6&6-rib Crank Pulley (7") 6322 Single 6-rib Water Pump Pulley (5 1/4") 208; Single 6-rib Alternator Pulley (2 3/4") All Mounting Hardware.
