Eagle Chevy 454 1P 4.000in Crank 6.135in I-Beam Rods 25.5cc Dome 4.320in Pistons Balanced Assembly

This is a balanced rotating assembly from Eagle for a Chevy 454 engine. It includes a 4.000-inch stroke crankshaft, 6.135-inch I-beam connecting rods, and 4.320-inch bore pistons with a 25.5cc dome volume. This assembly is pre-balanced, which saves you time and ensures proper engine operation when you're rebuilding your big-block Chevy.

Eagle is known for making well-built internal engine components, and this rotating assembly is no exception. The crankshaft is forged for strength, and the I-beam connecting rods are also forged, offering a solid option for performance builds. The pistons are designed with a 25.5cc dome, which will affect your compression ratio depending on your cylinder head volume. This assembly is balanced, meaning the crankshaft, rods, pistons, and bearings are all weighted and matched to work together smoothly, reducing vibration and stress on your engine's main bearings and other components. This is a critical step for any performance engine build to ensure longevity and optimal power delivery.

When installing this assembly, it's important to follow proper engine building procedures. This includes ensuring all bearing clearances are checked and within specification, using the correct assembly lube, and torquing all fasteners to the manufacturer's recommended settings. Because this assembly is balanced, it's crucial to use the correct balance weights if any modifications are made or if you're using a different flexplate or flywheel than what was used for the initial balancing. Please note that this assembly is not CARB approved and cannot be shipped to California.
