March Performance Chevy big block serpentine conversion kits simply bolt onto the front of any big block Chevy heads. Depending on the kit you choose, the alternator, A/C, and optional power steering will be either outward or mid-mounted. These pulleys are precision CNC-machined from solid billet 6061 T-6 aluminum to fit perfectly and handle high-torque and vibration. They are then clear powdercoated to eliminate polishing in those hard-to-reach places. These pulleys will not fracture like common cast pulleys, since they have high-tensile strength for much longer wear. The street rod ratio increases water flow and fan speed, which helps during critical low-speed driving. The kits are available with performance pulleys for increased horsepower, high water flow ratios for increased cooling, or mid-performance ratios for a combination of both.
