March Performance Chevy small block serpentine conversion kits are mid-mount pulley kits that place your alternator and power steering pump below the centerline of the water pump. They are simple to bolt on, while still retaining your standard-rotation long water pump. Serpentine belts eliminate belt throwing. 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. The pulleys are CNC-machined from solid billet 6061-T6 aluminum for a spectacular looking machine finish with a perfect fit and extra-high strength. All March Performance billet pulleys and brackets have a maintenance-free clear powdercoating. These performance pulleys will increase your engine by approximately 12-15 hp, depending on the accessories driven. The kits are available with a driver side mounted A/C option. The use of a combination bracket in these kits allows for the addition of an alternator idler, which provides excellent belt wrap around the alternator and A/C compressor pulleys.
