This is a complete rotating assembly from Eagle, specifically designed for Chevy 454 big-block engines. If you're building a high-performance street or dedicated race engine, this assembly gives you the core components needed to handle serious power. It includes a forged crankshaft, connecting rods, pistons, rings, and bearings, all balanced and ready for installation.

The heart of this assembly is a 4.250-inch forged 4340 steel crankshaft, known for its strength and durability under high stress. Paired with this are 6.385-inch H-beam connecting rods, which are a popular choice for their robust design and ability to withstand significant loads. These rods come equipped with 7/16-inch ARP 8740 bolts, a well-regarded fastener known for its reliability in performance applications. The pistons are forged 4032 aluminum from Mahle, featuring an 18cc dome design that works with specific cylinder head volumes to achieve your desired compression ratio. They come with plasma-moly file-fit rings, allowing for precise gap setting to match your engine's bore and intended use. To complete the package, King XP rod and main bearings are included, offering solid lubrication and wear protection for these critical rotating components.

This assembly is intended for racing use, including applications with nitrous oxide or forced induction. It's important to note that this part is not CARB approved and cannot be shipped to California. Proper installation by a qualified mechanic is recommended to ensure optimal performance and longevity.
