Chevy Small Block Serpentine Conversion
Pulley Sets, Replaces V-Belts

Standard Rotation Long & Short Water Pump Engine

Performance Ratios: Our performance serpentine pulley sets replace your Low performance V-belts and eliminate belt throwing while retaining your standard rotation water pump. Increases horsepower by reducing accessory drag. 12-15 h.p. at rear wheels typical. Precision CNC machined to run perfectly true. 6061-T6 aluminum for extra strength and wear. Finished with a “No Polishing” clear powdercoat.

 

Mid Performance Ratios: Uses performance crank pulley and high water flow water pump pulley.

 

High Water Flow Ratios: Increases cooling by speeding up water flow and fan speed. This helps at critical low speed driving where most overheating occurs. Precision CNC machined to run perfectly true. 6061-T6 aluminum for extra strength and wear. Finished with a “No Polishing” clear powdercoat.
