Description
A forged crankshaft is the backbone of any high-performance small block Chevy engine, and the Eagle SBC 4340 delivers the strength and reliability required for sustained boost, extended RPM limits, and aggressive power builds. The 3.480-inch stroke gives you optimal displacement and breathing characteristics without requiring complete engine redesign. When you’re building a motor that needs to survive serious power levels, internal balance and premium forged steel aren’t optional—they’re essential.
