About this part

Product Details

This Eagle rotating assembly starts with a 3.480-inch forged 4340 steel crankshaft, a solid foundation for building a serious Chevy 350 engine. The 4340 steel is known for its strength and durability, making it a popular choice for performance applications where reliability under stress is key. This assembly is designed to handle the demands of racing, including the extra pressures from nitrous and forced induction setups.

Paired with the crank are 6.000-inch H-beam connecting rods, secured with 7/16-inch ARP 8740 bolts. H-beam rods offer a strong yet relatively lightweight design, and the ARP bolts are well-regarded for their tensile strength and consistency, ensuring the rods stay firmly connected even under high RPM and load. The pistons are forged 4032 aluminum flat tops, featuring a -3.7cc dish to help achieve a desired compression ratio, and they measure 4.060 inches in bore diameter. These pistons come with plasma-moly standard gap rings, which help to create a good seal against the cylinder walls for improved performance and oil control. To complete the assembly, King XP rod and main bearings are included, offering robust performance and wear resistance for the critical rotating components.

This rotating assembly is a comprehensive package for anyone looking to build or rebuild a high-performance Chevy 350. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and break-in procedures.
