Designed for Chevy 348/409 applications. March Performance V-belt pulley kits keep the classic V-belt look while replacing worn or mismatched factory pulleys with a matched billet set. Each pulley is CNC-machined from 6061-T6 billet aluminum for a true-running, durable drive, and the matched ratios keep cooling and charging where they should be. It is an easy way to refresh an original-style engine without converting to serpentine.
This part number is configured as follows: Finish: Clear. Application: Chevy 348-409c.i. 5 1/2" Water Pump. Kit includes: 7901 1 Groove Crank Pulley (6 3/4") 7902 1 Groove Water Pump Pulley (6 1/2") 137; 1 Groove Alternator Pulley (2 11/32") All Mounting Hardware.
