SBC 4340 Forged Compstar Crank 3.500 Stroke

The SBC 4340 Forged Compstar Crank 3.500 Stroke by Callies is a premium crankshaft designed for serious small-block Chevy engine builders and performance enthusiasts. This forged steel component serves as the rotating foundation of any stroker motor, translating piston motion into usable power while handling extreme cylinder pressures and RPM loads. Whether you're assembling a street performance engine, bracket racing platform, or high-output marine application, a quality crankshaft is essential for reliability and longevity.

The 3.500-inch stroke dimension increases piston displacement compared to stock small-block specifications, allowing greater cubic-inch capacity and torque production without increasing engine bore size. Built from 4340 forged steel, this crankshaft exhibits superior fatigue resistance and impact strength compared to cast alternatives, which is critical for engines operating at elevated boost levels or sustained high RPM. The internal balance technology means counterweights are integrated into the crankshaft itself, streamlining assembly and reducing rotating mass.

This crankshaft is ideal for engine builders tackling stroker projects, drag racing applications, or any build requiring high performance. The two-piece rear seal design accommodates modern sealing standards while maintaining compatibility with traditional small-block Chevy architecture. With its robust construction and innovative design, the SBC 4340 Forged Compstar Crank is a reliable choice for enhancing engine performance.
