Eagle Chevy 409 4.000in Crank 6.135in H-Beam +.365in Edelbrock Dome 4.342in Piston Balanced Assembly

This Eagle rotating assembly starts with a 4.000-inch stroke crankshaft, designed for Chevy 409 applications. It's paired with 6.135-inch long H-beam connecting rods, known for their strength and ability to handle higher RPMs. The assembly includes 4.342-inch Edelbrock dome pistons, which are specifically chosen to work with this combination and achieve a particular compression ratio for your engine build.

This is a balanced assembly, meaning the crankshaft, rods, and pistons have been precisely weighted and matched at the factory. This balancing is crucial for reducing engine vibration and ensuring smoother operation, especially in high-performance or racing engines. The H-beam design of the connecting rods offers a solid structure that can withstand the significant forces generated during combustion, making it a popular choice for builds pushing beyond stock power levels. The dome piston design is integral to achieving the desired compression ratio when used with the specified crankshaft and rod length.

When building a performance engine, especially one based on the classic Chevy 409, a balanced rotating assembly like this one simplifies the process. It ensures that the critical internal components are properly matched from the start, saving you time and potential headaches during assembly. This assembly is intended for performance applications and is not CARB approved, meaning it cannot be shipped to California. Always consult your engine builder or performance specialist to ensure this assembly meets the specific requirements of your project.
