SBC Cast Steel Crank - 3.500 Stroke

The SBC Cast Steel Crank - 3.500 Stroke by SCAT ENTERPRISES is a precision-engineered crankshaft designed for small-block Chevrolet engines undergoing serious performance or rebuild work. This component forms the core of your engine's rotating assembly, converting reciprocating piston motion into rotational power delivered to the transmission and drivetrain. Whether you're restoring a classic muscle car, building a street engine, or upgrading an existing small-block platform, this cast steel crank provides the foundation for reliable, consistent power delivery across a wide RPM range.

Cast steel construction offers an excellent balance between durability and cost-effectiveness compared to forged alternatives, making it ideal for street and light-duty racing applications where extreme RPM limits are not required. The 3.500-inch stroke geometry defines the bore-to-stroke ratio of your engine build, directly influencing displacement, torque characteristics, and power band behavior—a longer stroke favors low-end torque and displacement volume. At 54 pounds, this crank carries sufficient mass to support smooth operation and consistent flywheel acceleration while maintaining compatibility with standard small-block engine blocks, bearing journals, and accessory packages. The precision manufacturing ensures proper balance, alignment, and bearing fit, critical factors that prevent premature wear and catastrophic engine failure.

Engine builders, restoration shops, and performance enthusiasts benefit most from this crank when assembling or refreshing small-block Chevrolet engines in the 350-400 cubic inch range. Installation requires professional engine building knowledge, proper machine work to verify bore alignment, and compatibility verification with your selected connecting rod length, piston design, and block specifications. Before purchasing, confirm that your engine block, main bearings, and rotating assembly components are compatible with a 3.500-stroke configuration, as this determines final displacement and performance characteristics of your completed engine.
