About this part

Product Details

This Eagle rotating assembly is built for Chevy 400 small block engines, specifically designed to increase displacement and power. It includes a 3.875-inch stroke crankshaft, 6.000-inch H-beam connecting rods, and -16cc dish pistons with a 4.125-inch bore. This combination effectively stroks the engine out, raising its displacement and improving its torque and horsepower potential for performance builds.

The heart of this assembly is the forged steel crankshaft, built to handle the increased stresses of a stroker combination. Paired with the strong H-beam connecting rods, which are known for their robust design and ability to withstand higher RPMs and loads, this assembly offers a solid foundation for a performance engine. The included pistons are designed with a -16cc dish to achieve a specific compression ratio when paired with the stroker crank and typical Chevy 400 cylinder heads, making it easier to tune for your desired performance level. This kit is a popular choice for builders looking to extract more power from their Chevy 400 platform.

When installing this rotating assembly, proper balancing is crucial to ensure smooth operation and longevity. It's recommended to have the complete assembly professionally balanced by a reputable machine shop before final engine assembly. Ensure all components are clean and properly lubricated during installation. Please note that this assembly is not CARB approved and cannot be shipped to California.
