Eagle Chevy 454 4.250in Crank 6.385in I-Beam Rods 23cc Dome 4.320in Pistons Balanced Assembly

Eagle is well-known for making strong internal engine components, and this balanced rotating assembly is a prime example for your Chevy 454. If you're building a street-driven vehicle that will see regular use, especially one that runs on pump gas and isn't force-fed air, this assembly is designed to handle it. It's a complete package that takes the guesswork out of matching critical rotating parts.

This assembly starts with a 4.250-inch cast crankshaft, providing the foundation for increased displacement. Paired with it are 6.385-inch I-beam connecting rods, which are secured with 7/16-inch ARP 8740 bolts for reliable clamping force. The pistons are forged 4032 aluminum from Icon, featuring a 23cc dome and a 4.320-inch bore size, designed to work with pump gas in naturally aspirated setups. They come with plasma-moly file-fit rings, giving you the flexibility to achieve a precise seal in the cylinder bore. To top it off, King SI rod and main bearings are included, offering solid lubrication and wear resistance for the crankshaft journals.

This assembly comes balanced from the factory, which is a crucial step for smooth engine operation and longevity, especially at higher RPMs. 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.
