Eagle Chevy 427/454 3.766in Crank 6.135in I-Beam Rods 41cc Dome 4.350in Pistons Rotating Assembly

Eagle is well-known for building robust engine components, and their Pro Street Rotating Assemblies are a prime example of that commitment. This particular assembly is designed for Chevy 427 and 454 big-block engines, offering a solid foundation for naturally-aspirated racing applications. It's a comprehensive package that brings together all the critical rotating parts you need to rebuild or upgrade your engine's core.

At the heart of this assembly is a 3.766-inch forged 4340 crankshaft, chosen for its strength and durability under demanding conditions. Paired with it are 6.135-inch I-beam connecting rods, also made from strong 4340 steel, and they come equipped with 7/16-inch ARP 8740 bolts to ensure a secure connection. For the pistons, you get forged 4032 aluminum pistons from ICON, featuring a 41cc dome and a 4.350-inch bore size, designed to work with the crank and rods for optimal compression and performance in a naturally aspirated setup. The assembly also includes plasma-moly file-fit piston rings, which allow for precise gap setting to match your specific engine build, and King XP series rod and main bearings, known for their excellent performance and wear resistance.

This rotating assembly is a significant step up for anyone looking to build a powerful, naturally aspirated racing engine. Please note that this assembly is not CARB approved and cannot be shipped to California. It also carries a Prop 65 warning.
