Description

The Callies Performance Products IBP-425-CS is a Compstar Performance Crankshaft for Big Block Chevy engines. It is made from 4340 forged steel, rough machined to Callies' specifications, and finished in-house. This design optimizes balance and reduces bearing loads. The forgings undergo double stress relief for dimensional stability, and a deep nitride hardening process makes them suitable for demanding applications like dirt track racing. It is a 4.250-inch stroke model, weighs 74 lbs, and is fully counterweighted for high RPM, high output engine builds.
