SBF 351W Cast Steel Crank - 3.500 Stroke

The SBF 351W Cast Steel Crank with 3.500 stroke is a core rotating assembly component engineered for Ford 351W small-block engine builds seeking reliable bottom-end performance. This crankshaft is essential for high-revving stroker or performance motors, controlling piston travel and determining engine displacement when paired with compatible rod and piston combinations.

Constructed from cast steel, this crankshaft offers an excellent balance between cost-effectiveness and strength, making it suitable for naturally aspirated and moderately boosted engines. The 3.500 stroke lengthens the piston dwell in the cylinder, enhancing torque production and overall performance. Weighing 58.3 lbs, this crank maintains manageable rotating mass while providing robust journal diameters and counterweight design to handle increased cylinder pressures and higher RPM loads.

Engine builders favor this stroker crank when assembling 408–427 cubic inch combinations from the 351W block, a popular choice in hot rod, truck, and performance boat applications. Compatibility with specific rod lengths is essential for optimal performance, ensuring that builders achieve the desired engine characteristics.
