Eagle Chevy 454 1Pc 4.000in Crank 6.385in H-Beam -3cc Flat Top 4.280in Pistons Rotating Assembly

This Eagle rotating assembly gives you the core components to build a serious Chevy 454 engine. You get a 4.000-inch forged 4340 crankshaft, a set of 6.385-inch H-beam connecting rods, and a complete set of JE pistons designed for forced induction. It also includes plasma-moly file-fit piston rings and King XP rod and main bearings to get your build started right.

Eagle builds these assemblies for extreme competition, meaning they're ready for heavy nitrous use, high boost, or exotic fuels. The forged 4340 steel crankshaft is a strong foundation, and the H-beam rods are well-built for high stress. The JE pistons are forged from 2618 aluminum and feature a -3cc flat top dish, making them ideal for forced induction setups. The included plasma-moly rings are designed to be file-fit, allowing you to achieve precise piston-to-wall clearance for optimal sealing, especially under boost. King XP bearings are known for their durability and performance in demanding applications.

This assembly is a solid starting point for a high-performance 454 build. Keep in mind 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.
