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 4.000"; Stroke, which should be cross-checked against the rest of the engine combination.
For Chevrolet Big Block, do not treat stroke as the only fitment check. Journal dimensions, trigger arrangement, block clearance, balancing, and the chosen rods and pistons all need to agree with this crankshaft.
