Eagle forged 4340 steel crankshaft for Chevrolet 400 with a 3.480" stroke in an internal balance configuration. The crank employs a non-twist forging and .125" fillet radiuses for added strength, which require chamfered or narrowed bearings. Nitrided journals and a micropolished finish enhance wear resistance and running quality for demanding engine applications.
