Eagle Chevrolet 350 3.250in Stroke Large Journal Forged 4340 Steel Crankshaft

What you get here is a robust, forged 4340 steel crankshaft from Eagle, specifically designed for Chevrolet 350 engines with large journal configurations. This crankshaft features a 3.250-inch stroke, making it a solid choice for rebuilding or upgrading your engine's bottom end. It's built with a non-twist forging process and .125-inch fillet radii, which are chamfered or narrowed to accept specific bearings, adding significant strength to the critical journal areas.

Eagle treats this crankshaft with a nitriding surface treatment and a micropolish finish. Nitriding hardens the surface, making it more resistant to wear and fatigue, while the micropolish ensures a smooth finish for optimal bearing performance and longevity. These treatments are crucial for engines that will be pushed hard, ensuring the crankshaft can handle the stress of high RPMs and increased power output. This part is intended for demanding applications where reliability and strength are paramount.

This crankshaft is designed to fit a wide range of Chevrolet vehicles, including popular models like the 1969-1975 Chevrolet Bel Air, 1988-1999 Chevrolet C1500, and 1967-1993 Chevrolet Camaro. When undertaking an engine build of this caliber, ensure you have the correct supporting components, such as appropriate pistons, connecting rods, and bearings that match the large journal and narrowed fillet radius specifications. Always refer to the manufacturer's installation instructions for precise details on assembly and bearing selection.
