Eagle Chevy 454 4.000in Crank 6.135in H-Beam 18.3cc Dome 4.280in Pistons Rotating Assembly

This is the Eagle 11420L030 rotating assembly, built for serious performance in Chevy 454 engines. If you're putting together a competition engine, whether for drag racing, street-strip use, or even a serious street build that demands robust components, a strong rotating assembly is the heart of it all. This package includes a forged 4.000-inch crankshaft, 6.135-inch H-beam connecting rods with 7/16-inch ARP 8740 bolts, and 4.280-inch forged 4032 Icon pistons with an 18.3cc closed chamber dome. It's designed to handle the stresses of high-RPM operation and increased cylinder pressures.

The forged 4340 steel crankshaft is a solid foundation, offering improved strength and durability over cast cranks, which is crucial when you're pushing the limits. The H-beam connecting rods are also forged, providing a strong link between the crank and pistons, and they come equipped with ARP 8740 bolts, known for their reliability in high-stress applications. The Icon pistons are forged from 4032 aluminum, a material that balances strength with a good expansion rate for tighter piston-to-wall clearances, and the 18.3cc dome is designed to work with specific compression ratios. This assembly also includes plasma-moly file-fit piston rings, which allow for precise gapping to match your engine's bore and intended use, and King XP rod and main bearings, which are well-regarded for their performance in demanding builds.

When assembling an engine of this caliber, attention to detail is key. The plasma-moly rings are file-fit, meaning you'll need to gap them to your specific engine's bore and intended use – this is a standard procedure for performance builds to ensure optimal sealing and performance. This rotating assembly is intended for competition use and is not CARB approved, so it cannot be shipped to California. It's a well-built package designed to be the core of a powerful, high-performance engine.
