Description
For Chevrolet Big Block Non - Twist Forgings engine builds, this Manley crankshaft should be selected around stroke, journal configuration, trigger compatibility, and the piston/rod package being used with it. The parent listing is distinguished by 4.250"; Stroke, which should be cross-checked against the rest of the engine combination.
For Chevrolet Big Block Non - Twist Forgings, 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.
