This is a balanced rotating assembly from Eagle, specifically designed for Chevy 454 and 502 big-block engines. It includes a forged 4.250-inch crankshaft, 6.385-inch H-beam connecting rods with ARP 7/16-inch bolts, Mahle 4.310-inch flat-top pistons with a -3cc dish, plasma-moly file-fit piston rings, and King XP rod and main bearings. This assembly is balanced and ready for installation, making it a solid choice for serious engine builds, including those using nitrous or forced induction.

The forged 4340 steel crankshaft offers improved strength and durability over cast cranks, essential for handling the increased stresses of high-performance applications. The H-beam connecting rods are well-built and paired with reliable ARP 8740 bolts, ensuring they can withstand significant loads. The Mahle pistons are forged from 4032 aluminum, known for its good thermal expansion properties, and feature a flat-top design with a -3cc volume, which will affect your compression ratio depending on your cylinder heads. The included plasma-moly file-fit rings allow for precise gapping to match your specific engine build, and the King XP bearings are designed for high-performance lubrication needs.

This balanced rotating assembly is a critical component for anyone looking to build a powerful and reliable engine. It’s important to note that this assembly is not CARB approved and cannot be shipped to California.
