Eagle SBC 350 Forged Crankshaft 3.480in Stroke 2.1in Rod Journal

This is an Eagle 4340 forged steel crankshaft designed for Chevrolet 305 and 350 engines. It features a 3.480-inch stroke and 2.1-inch rod journals, specifically engineered for competition use where reducing rotating weight is critical for performance. The non-twist forging process and lightweight counterweight design help minimize overall mass, allowing for quicker engine response.

Constructed from forged 4340 steel, this crankshaft is built for strength. It includes .125-inch fillet radii, which means you'll need to use chamfered or narrowed bearings for proper installation. The surface is nitrided and micropolished for improved durability and smoother operation. This crankshaft is intended for restricted-class competition builds, and it requires lightweight rods and pistons to achieve optimal balance.

When building a high-performance engine for competition, selecting the right crankshaft is crucial. This Eagle crankshaft offers a robust foundation for builds focused on reducing internal friction and increasing responsiveness. Remember to consult your engine builder or refer to the manufacturer's installation guidelines for specific bearing requirements and balancing procedures.
