Eagle Chevy 454 1Pc 4.250in Crank 6.385in H-Beam 15cc Dome 4.280in Pistons Rotating Assembly

This is a complete rotating assembly from Eagle, specifically built for Chevy 454 engines. It includes a 1-piece rear main seal 4.250-inch crankshaft, 6.385-inch H-beam connecting rods, and 4.280-inch, 15cc dome pistons. This assembly is designed to handle increased performance demands, making it a solid choice for engine rebuilds or upgrades where more power is the goal.

The heart of this assembly is the forged crankshaft, known for its strength and durability under high stress. Paired with the robust H-beam connecting rods, which offer a strong balance between weight and rigidity, this setup is built to withstand the rigors of performance applications. The 15cc dome pistons are designed to work with specific cylinder head volumes to achieve a target compression ratio, typically around 10.5:1 with 118cc heads, though this can vary. This combination is crucial for optimizing combustion efficiency and power output in a performance engine build.

This rotating assembly is a significant upgrade for your Chevy 454. It's important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and balancing procedures, as a balanced rotating assembly is critical for engine longevity and smooth operation.
