Eagle 67-86 Chevrolet Small Block V8 5.7L 350 Forged Crankshaft - 4340 Steel 3.875in Strk 2-Pce Seal

Eagle is well-known for making strong engine components, and this forged crankshaft is a prime example of their commitment to durability. If you're building or rebuilding a Chevrolet Small Block V8 engine, especially a 5.7L 350, this crankshaft is built to handle serious power. It's designed with a 3.875-inch stroke, which is a common choice for increasing displacement and torque in these popular Chevy engines.

This crankshaft is forged from 4340 steel, a material chosen for its exceptional strength and reliability under high stress. Eagle uses a non-twist forging process and adds .125-inch fillet radii, which significantly increases its strength. Because of these strengthened radii, you'll need to use chamfered or narrowed bearings when installing this crank. The surface is also nitrided and micropolished, further enhancing its durability and ensuring smooth operation with your bearings.

This crankshaft is internally balanced and designed for a 2-piece rear main seal, which is standard for many Chevrolet Small Block V8s from 1967-1986. It's a solid choice for builds where reliability and performance are critical. Remember to consult your engine's specific service manual for detailed installation procedures and bearing specifications.
