Description
This Manley crankshaft family targets Chevrolet Big Block; the listed stroke is a core build dimension and should be verified against the complete short-block specification before purchase. The parent listing is distinguished by 4.625"; 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.
