March Performance Chevy Big Block Serpentine Conversion Kits
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.
