302-351 Windsor/Clevld. Crank Pulley 2 Groove

The MARCH PERFORMANCE 302-351 Windsor/Cleveland Crank Pulley with a 2-groove design is an essential component for small-block and big-block Ford engine swaps. This crank pulley is ideal for those restoring classic muscle cars, upgrading street machines, or building high-performance engine bays. It effectively manages critical crankshaft harmonics while allowing for dual serpentine belt compatibility.

Designed specifically for 302 and 351 Windsor blocks, as well as Cleveland variants, this crank pulley addresses the need for modern accessory drive integration. The two-groove configuration enables the simultaneous operation of alternator, power steering, and air conditioning belts, eliminating the fitment headaches associated with single-groove designs. With a diameter of 6.3 inches, this pulley is engineered to maintain proper harmonic damping, which is critical for engine longevity.

Engine builders and classic Ford enthusiasts will find this pulley particularly beneficial when consolidating multiple accessory systems into a clean, single-component solution. The lightweight design, weighing 2.1 lbs, optimizes performance and weight distribution, while the grooved profile ensures positive belt tracking and reduces slippage under load. This makes it an excellent choice for those running high-output alternators or accessory-heavy configurations.
