Eagle Chevy 454 1Pc 4.000in Crank 6.135in I-Beam Rod -3cc Flat Top 4.280in Pistons Balanced Assembly

If you're rebuilding the heart of your Chevy 454 for street use, this balanced rotating assembly from Eagle is a solid foundation. It's designed for pump gas, naturally aspirated applications, meaning it's built to perform reliably on the street without needing exotic fuel. This assembly takes the guesswork out of matching critical internal engine components, ensuring they work together harmoniously right out of the box.

At the core of this assembly is a 4.000-inch cast crankshaft, paired with 6.135-inch I-beam connecting rods. These rods are secured with 7/16-inch ARP 8740 bolts, a well-known name for strong, reliable hardware. The pistons are forged 4032 aluminum from Icon, featuring a -3cc flat top design and a 4.280-inch bore size, which are crucial for achieving your desired compression ratio. This assembly also includes plasma-moly file-fit piston rings, allowing for precise ring gap adjustment during installation, and King rod and main bearings to ensure smooth rotation and proper oil clearance.

This rotating assembly comes balanced from Eagle, which is a significant step that saves you time and ensures the engine runs smoothly. Balancing is critical for reducing vibration and extending the life of your engine, 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 break-in procedures.
