Description
This Manley crankshaft is listed for Chevrolet Big Block, with the stroke and part-family information in the title defining the rotating-assembly combination it belongs to. The parent listing is distinguished by 4.375"; Stroke, which should be cross-checked against the rest of the engine combination.
A crankshaft change on Chevrolet Big Block can alter displacement, piston compression-height requirements, counterweight clearance, and balance strategy, so the complete rotating assembly should be planned as a system.
