SBC Long w/p Serpentine Conversion Pulley Kit

The SBC Long w/p Serpentine Conversion Pulley Kit from MARCH PERFORMANCE is a complete pulley system engineered for small-block Chevrolet engines seeking modernized belt-drive efficiency and a polished appearance. This conversion kit replaces traditional multi-belt setups with a single serpentine belt configuration, simplifying engine bay layout while maintaining reliable power delivery to essential accessories. Builders and restorers choose this kit to achieve a cleaner, more contemporary look without sacrificing cooling or charging system performance.

Constructed from lightweight aluminum and finished in a durable clear powder coat, the SBC Long w/p Serpentine Conversion Pulley Kit features a six-rib belt design that maximizes grip and load distribution across the serpentine belt. The long water pump configuration accommodates deep-block Chevrolet engines, allowing the pulley assembly to integrate seamlessly with high-displacement or stroker applications. Ultra-performance tuning ensures minimal parasitic drag, preserving horsepower while the hardened aluminum construction resists corrosion and thermal stress in high-heat engine compartments.

This pulley kit is ideal for street rods, classic car restorations, and performance-oriented small-block Chevy builds where factory serpentine conversion or upgraded accessory drive systems are desired. Installation requires basic mechanical knowledge and compatibility with a long-style water pump housing. Enthusiasts appreciate the factory-finished aesthetic that complements modern underhood detailing while the serpentine belt reduces maintenance intervals compared to traditional v-belt systems.
