SBC 4340 Forged Crank - 3.250 Stroke

The SBC 4340 Forged Crank - 3.250 Stroke by SCAT ENTERPRISES is a premium rotating assembly component designed for small-block Chevrolet engine builders and performance enthusiasts. This forged crankshaft is engineered for high-performance applications, making it suitable for street machines, race engines, and forced-induction builds that require a robust bottom-end architecture.

Constructed from 4340 alloy steel, this crankshaft offers superior tensile strength and fatigue resistance compared to cast alternatives, allowing it to endure the stresses of high RPM operation and aggressive ignition timing. The 3.250-inch stroke geometry provides a balanced bore-to-stroke ratio, optimizing torque characteristics while maintaining high RPM capability. SCAT ENTERPRISES' precision manufacturing ensures tight tolerances on all journals and crank pins, which is critical for minimizing bearing wear.

This crankshaft is compatible with various small-block configurations, including 350 cubic-inch builds, where the 3.250-inch stroke pairs well with standard bore sizing to deliver reliable performance. Proper installation requires balancing with your specific rotating assembly mass, harmonic balancer selection, and flywheel, making professional engine assembly highly recommended for optimal results.
