Eagle Chevy 427/454 3.766in Crank 6.135in I-Beam Rods 4.280in Pistons Rotating Assembly

This Eagle Pro Street Rotating Assembly gives you the core components to rebuild or upgrade the heart of your Chevy 427 or 454 engine. What you get in this kit is a 3.766-inch forged 4340 crankshaft, a set of 6.135-inch 4340 I-beam connecting rods, and 4.280-inch forged 4032 Icon pistons with a 28.2cc closed chamber dome. It also includes plasma-moly file-fit piston rings and King XP rod and main bearings to get you started.

This assembly is built for naturally-aspirated racing applications, meaning it's designed to handle the demands of high-RPM operation without forced induction. The forged 4340 steel crank and rods are well-built for strength and durability under stress. The Icon pistons are forged from 4032 aluminum, which offers a good balance of strength and thermal expansion properties for performance builds. The included 7/16-inch ARP 8740 bolts for the connecting rods are a strong choice for ensuring reliable rod cap retention. The file-fit plasma-moly rings allow for precise gapping to match your specific cylinder wall finish and desired clearances, which is crucial for optimal sealing and performance in a race engine.

When putting this assembly together, remember that the file-fit rings will need to be gapped to your engine's specific requirements. This kit is intended for racing use and is not CARB approved, so it cannot be shipped to California. Always consult manufacturer instructions for proper assembly and installation procedures to ensure the longevity and performance of your engine.
