Eagle Chevy 454 1P 4.000in Crank 6.135in I-Beam Rods 28cc Dome 4.310in Pistons Balanced Assembly

This is a balanced rotating assembly from Eagle, specifically built for Chevy 454 engines. It includes a 4.000-inch stroke crankshaft, 6.135-inch I-beam connecting rods, and 28cc dome pistons with a 4.310-inch bore. This assembly is a crucial starting point for anyone rebuilding or significantly upgrading their big-block Chevy engine, aiming for increased displacement and robust performance.

Eagle is known for producing well-built internal engine components, and this balanced assembly is no exception. The I-beam connecting rods offer a strong and reliable connection between the piston and crankshaft, suitable for performance applications. The 4.000-inch stroke crankshaft, combined with the 4.310-inch bore pistons, results in a larger displacement for your 454, which generally translates to more torque and horsepower. The 28cc dome piston design is specific to certain compression ratio targets, so it's important to consider your cylinder head volume when planning your build. Having the assembly balanced from the factory means Eagle has taken the time to ensure the rotating mass is properly weighted, which is critical for engine longevity and smooth operation at higher RPMs. This reduces vibration and stress on bearings and other internal components.

When installing this rotating assembly, it's essential to follow proper machining and assembly procedures. This includes ensuring your engine block is bored and honed to the correct piston diameter, and that all bearing clearances are checked and within specification. This assembly is not CARB approved and cannot be shipped to California. Always consult your engine builder or a trusted mechanic for specific installation requirements and recommendations for your particular build.
