Info
Callies solid modeling abilities provide a great advantage in Small Block Chevy 383 crankshaft development. They’re able to precisely locate material where it will yield the greatest advantage in terms of both strength to weight, and balance ability.

Beginning with properly placed counterweights that not only improve balance but reduce bearing loads, every aspect of these highly stressed components has been analyzed. The forgings are rough machined in a process that includes double stress relief operations that make these crankshafts very dimensionally stable.

Hardened with a deep nitride, Compstar cranks are ideal for all types of abusive racing environments. All rod journals are drilled and counterweights are profiled for piston clearance. With a consistent grind and polish, along with precise stroke and index, you will see why we say these crankshafts are Compstar Correct!
