The Small Block Ford Deluxe Serpentine Conversion Kit from March Performance delivers race-proven engineering and street-ready reliability for 1979–1993 Ford 289, 302, and 351 Windsor engines. Each component is CNC-machined from 6061-T6 billet aluminum, providing exceptional strength, precision fitment, and vibration resistance. Matching 6-rib serpentine pulleys are hard-coated to 65 Rockwell hardness — tougher than steel — ensuring durability and long life. Available in high water flow (for daily drivers) or performance ratios (for race builds), this system optimizes both cooling and horsepower. Finished with a maintenance-free powder coat, it eliminates the need for polishing while offering a show-quality appearance. Complete with stainless tensioning rods, premium hardware, and all necessary brackets, this American-made serpentine system sets the benchmark for Ford small block performance and reliability.
