This is a balanced rotating assembly from Eagle, specifically built for Chevy 454 tall deck engines. It includes a forged 4340 crankshaft with a 4.500-inch stroke, H-beam connecting rods that are 6.660 inches long and use 7/16-inch ARP 8740 bolts, and forged 2618 Mahle pistons with an 18cc dome and a 4.310-inch bore. This assembly is ready for serious performance builds, including those using nitrous or forced induction.

The forged 4340 steel crankshaft is a strong foundation for high-horsepower applications, offering excellent durability under stress. The 6.660-inch H-beam connecting rods are well-known for their strength and are paired with high-quality ARP 8740 bolts, ensuring reliable performance even in demanding racing conditions. The Mahle pistons are forged from 2618 aluminum, a material chosen for its strength and ability to handle high temperatures and pressures, and feature an 18cc dome to achieve a specific compression ratio when paired with the right cylinder heads. This assembly also comes with plasma-moly file-fit rings, which allow for precise gap setting to optimize sealing and performance, and King XP rod and main bearings, known for their robust construction and ability to handle heavy loads.

This balanced assembly is designed to reduce vibration and improve overall engine smoothness, especially at higher RPMs. It's important to note that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations.
