March Performance Ford 302-351W/C Serpentine Conversion Kits
Increase horsepower and eliminate belt throwing with March Performance Ford 302-351 Windsor and Cleveland serpentine conversion pulley kits. These simple-to-bolt-on pulleys replace your low-performance V-belt pulleys, while retaining your standard rotation water pump. They are CNC-machined from solid billet 6061 T-6 aluminum for extra strength and wear, and are covered with a no-polish clear powdercoated finish. They come available in Performance series and high water flow style pulleys to suit your needs. Performance series pulleys create approximately 12.5 to 15 hp at the rear wheels by reducing accessory drag. They also eliminate belt throwing and are designed for normal street driving. High water flow pulleys increase cooling by speeding up water flow and fan speed. This helps at critical low-speed driving, where most overheating occurs.
