Product Details

If you're building a high-performance Chevy 454 engine for serious racing, especially with nitrous or forced induction, a strong rotating assembly is the heart of your build. This Eagle Competition Rotating Assembly is designed to handle the extreme demands of competition, providing a solid foundation for your engine's power output. It brings together key components that work in harmony to convert combustion pressure into reliable rotational force.

At the core of this assembly is a 4.250-inch forged 4340 steel crankshaft, chosen for its strength and durability under high stress. Paired with this are 6.385-inch H-beam connecting rods, known for their robust design, which utilize 7/16-inch ARP 8740 bolts for secure attachment. The pistons are forged 4032 aluminum from ICON, featuring a 23cc dome shape and a 4.280-inch bore size, designed to work with specific compression ratios. This assembly also includes plasma-moly file-fit piston rings, allowing for precise gap setting to optimize performance and sealing, along with King XP rod and main bearings, which offer enhanced durability and reduced friction for competition applications.

This is a comprehensive package for engine builders focused on maximizing performance and reliability in racing environments.
