      Fits: Chevrolet 396-454, pre-1969 (with short water pump)

      Precision machined from high grade, lightweight aluminum castings

      Extra-deep belt grooves provide added belt retention during rapid changes in engine RPM
      Small pulley diameter slows fan, water pump, and alternator speed to reduce horsepower-robbing drag
