About this part

Product Details

When you're building a high-performance Chevy 454 engine, especially one intended for racing applications like nitrous or forced induction, the rotating assembly is the heart of the operation. This Eagle Competition Rotating Assembly is designed to handle the extreme stresses these types of builds demand. It's a complete package that ensures your engine's core components are well-matched and built for durability under pressure.

This assembly starts with a 4.250-inch forged 4340 crankshaft, a strong foundation for significant power. Paired with it are 6.385-inch H-beam connecting rods, known for their robust construction and ability to withstand high RPMs and heavy loads. These rods come with 7/16-inch ARP 8740 bolts, a well-regarded choice for their strength and reliability in demanding applications. The pistons are forged 4032 ICON units, featuring a 23cc dome and a 4.250-inch bore size, designed to work seamlessly with the crank and rods. Topping it off are plasma-moly file-fit rings and King XP rod and main bearings, providing excellent sealing and smooth operation. This combination is built for serious performance where reliability is just as important as power.

It's important to note that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations. When installing, ensure you follow all manufacturer guidelines for proper assembly and break-in procedures to get the most out of this competition-grade rotating assembly.
