About this part

Product Details

If you're building a high-performance Chevy 454 engine for serious racing, a robust rotating assembly is the heart of your build. This Eagle competition rotating assembly is designed to handle the demands of racing, including applications using nitrous or forced induction. It's a well-built foundation for an engine that needs to perform under pressure.

This assembly starts with a 4.250-inch forged 4340 crankshaft, known for its strength and durability in high-stress environments. Paired with this are 6.385-inch H-beam connecting rods, which are a popular choice for their strong I-beam design that resists bending and flexing. These rods are secured with 7/16-inch ARP 8740 bolts, a name trusted for their reliability in high-performance engine builds. The pistons are forged 4032 aluminum from ICON, featuring a 23cc dome shape and a 4.320-inch bore size, designed to work with the crank and rod combination for optimal compression and performance. The assembly also includes plasma-moly file-fit piston rings, allowing for precise ring gap adjustment to match your specific engine build and tuning needs. Finally, it comes complete with King XP rod and main bearings, offering improved performance and durability for critical rotating components.

This rotating assembly is intended for competition use and is not CARB approved, meaning it cannot be shipped to California. Ensure you have the necessary supporting components and expertise for installation, as this is a critical part of a performance engine build.
