Eagle Chevy 454 4.000in Crank 6.135in I-Beam Rods -3cc Flat Top 4.320in Pistons Balanced Assembly

This balanced rotating assembly from Eagle is built for Chevy 454 engines, specifically designed for street vehicles running on pump gas and naturally aspirated setups. What you get in this package is a complete, balanced rotating assembly ready to be installed into your engine block. It includes a 4.000-inch cast crankshaft, 6.135-inch I-beam connecting rods secured with 7/16-inch ARP 8740 bolts, hypereutectic KB flat-top pistons with a -3cc dish, plasma-moly file-fit piston rings, and King SI rod and main bearings.

The I-beam connecting rods are a solid choice for street performance, offering a good balance of strength and weight. The included KB pistons are hypereutectic, a well-regarded material for street applications that offers improved strength over cast pistons while remaining more affordable than forged options. The -3cc flat top design is common for naturally aspirated builds, helping to achieve a desired compression ratio with typical cylinder heads. Eagle has also balanced this assembly, which is a crucial step to ensure smooth engine operation and reduce vibration at higher RPMs. This saves you a significant amount of labor and ensures the rotating assembly is ready to go.

This assembly comes with King SI series bearings, known for their reliable performance in street applications. The plasma-moly file-fit rings give you the flexibility to achieve a perfect seal with your cylinder walls, which is essential for good compression and oil control. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. It's important to verify fitment with your specific engine block and cylinder heads to ensure proper installation and optimal performance.
