SBF 4340 Forged Crank - 3.400 Stroke

The SBF 4340 Forged Crank with 3.400 stroke is a precision-engineered crankshaft designed for small block Ford engine builds demanding durability and reliability. Built by SCAT ENTERPRISES, a trusted name in high-performance engine components, this forged steel crank serves both stock restoration projects and modified powerplants where strength and longevity are non-negotiable.

This crankshaft features a 3.400-inch stroke dimension, defining the piston's travel distance and directly influencing engine displacement and low-end torque characteristics. The forged 4340 steel construction provides superior tensile strength and fatigue resistance compared to cast alternatives, critical for handling high RPM loads and maintaining structural integrity under sustained performance conditions.

Technicians and engine builders working on small block Ford platforms—including 289, 302, 351W, and related displacements—will find this crankshaft compatible with both 1-piece and 2-piece seal configurations. Its internal balance design eliminates the need for external counterweights, reducing parasitic drag and improving overall efficiency while ensuring compatibility with factory and aftermarket internal components.
