Eagle Chevy 396 4.000in Crank 6.135in H-Beam 17cc Dome 4.135in Pistons Balanced Assembly

If you're rebuilding a Chevy 396 big block for serious performance, a balanced rotating assembly is the foundation for a smooth-running, powerful engine. This assembly from Eagle is built around a 4.000-inch stroke crankshaft, paired with 6.135-inch H-beam connecting rods and 4.135-inch, 17cc dome pistons. Everything is balanced together as a complete unit, which is crucial for reducing vibration and allowing the engine to rev more freely and safely.

Eagle is known for making well-built internal engine components, and this assembly is no exception. The H-beam rods are a strong choice for performance applications, offering a good balance of strength and weight. The pistons are designed with a 17cc dome, which will increase the compression ratio when used with appropriate cylinder heads, contributing to more power. Having the entire assembly balanced from the factory means you save significant time and ensure the critical internal balance needed for high-RPM operation. This takes the guesswork out of balancing your rotating assembly, a vital step for any performance build.

This balanced rotating assembly is a significant upgrade for your Chevy 396. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and torque specifications when putting this into your engine block.
