Eagle Chevy 454 4.000in Crank 6.135in H-Beam 18cc Closed Chamber 4.320in Pistons Rotating Assembly

Eagle is well-known for building robust engine components, and this rotating assembly for the Chevy 454 is a prime example of their commitment to performance. If you're looking to build a serious engine for racing, whether it's naturally aspirated, running nitrous, or using forced induction, this assembly is designed to handle the stress. It includes all the core pieces you need to get your short block started, giving you a solid foundation for a high-output 454.

At the heart of this assembly is a 4.000-inch stroke forged 4340 crankshaft, chosen for its strength and durability under extreme loads. Paired with this are 6.135-inch H-beam connecting rods, which are also forged from 4340 steel and come equipped with 7/16-inch ARP 8740 bolts for a secure and reliable connection. The pistons are forged 2618 aluminum from ICON, featuring an 18cc closed chamber dome design and a 4.320-inch bore size, ready for your specific compression ratio needs. This kit also includes plasma-moly file-fit rings, which allow for precise gapping to match your cylinder wall finish and intended use, and King XP rod and main bearings, known for their excellent performance and wear resistance in demanding applications.

This is a competition-level assembly, meaning it's built with materials and tolerances suited for high-RPM, high-stress environments. Remember that this assembly is not CARB approved and cannot be shipped to California. You'll want to ensure you have the proper tools and knowledge for installation, as precise balancing and assembly are critical for engine longevity and performance.
