Ford 351W V-Belt/Serp Conv

The Ford 351W V-Belt/Serp Conv from March Performance is a precision serpentine belt conversion system designed for classic and modern Ford 351W Windsor engine builds. This conversion eliminates the traditional V-belt setup and replaces it with a modern serpentine belt configuration, offering superior reliability and reduced maintenance intervals. Whether you're restoring a vintage Mustang, Bronco, or Torino, or upgrading a contemporary 351W swap, this conversion transforms engine accessory drive efficiency and longevity.

March Performance engineered this conversion kit to leverage the advantages of serpentine belt technology: single-belt simplicity, reduced parasitic drag, and quieter operation compared to multi-groove V-belt systems. The compact design (7.3 x 5.65 x 7.35 inches) and lightweight construction at just 1.98 lbs minimize vibration transfer to the engine block while maximizing belt contact and grip during high-RPM operation. This conversion is ideal for enthusiasts who demand cleaner engine bay aesthetics and predictable accessory performance in street, strip, or show applications.

The Ford 351W V-Belt/Serp Conv works seamlessly with stock or modified 351W engines and accommodates both naturally aspirated and supercharged configurations. This conversion is particularly beneficial for those looking to enhance their engine's performance while maintaining a tidy engine bay. With its modern design, it provides a reliable solution for various applications, ensuring that engine accessories operate efficiently.
