Eagle Chevy 454 4.000in Crank 6.135in H-Beam -3cc Flat Top 4.280in Pistons Rotating Assembly

Eagle is a well-known name in the performance engine world, especially for building robust rotating assemblies that can handle serious power. This particular assembly is built for the Chevy 454 big block, giving you a solid foundation for a high-performance engine build. Whether you're aiming for the drag strip, a track car, or just want a serious street machine, this kit is designed to take a beating.

At the heart of this assembly is a 4.000-inch forged 4340 steel crankshaft. Forged cranks are much stronger than cast ones, making them essential for engines that will see high RPMs or significant stress from forced induction or nitrous. The connecting rods are 6.135-inch H-beam units, also forged from 4340 steel, and they come with 7/16-inch ARP 8740 bolts. ARP bolts are a popular choice for their strength and reliability. The pistons are forged 4032 aluminum from ICON, featuring a -3cc flat top design and a 4.280-inch bore size, which is standard for many 454 applications. These pistons are paired with plasma-moly file-fit rings, allowing for precise gap setting during installation to optimize performance and sealing. To top it off, the assembly includes King XP rod and main bearings, known for their durability and performance under load.

This rotating assembly is intended for competition use and is not CARB approved, meaning it cannot be shipped to California. It's a serious component for serious engine builds, providing the strength and reliability needed for boosted or nitrous-fed applications. You'll want to ensure you have the correct machine work done on your block to accommodate these components, especially for the piston ring gap and bearing clearances.
