Eagle Chevy 454 4.000in Crank 6.135in I-Beam Rods -3cc Flat Top 4.320in Pistons Rotating Assembly

This Eagle Pro Street Rotating Assembly gives you the core components to rebuild or upgrade your Chevy 454 engine. What you get in this kit is a 4.000-inch forged 4340 crankshaft, a set of 6.135-inch 4340 I-beam connecting rods, and 4.320-inch flat-top pistons from ICON with a -3cc dish. It also includes plasma-moly file-fit piston rings and KING XP rod and main bearings to get your rotating assembly ready for installation.

This assembly is built for naturally-aspirated racing applications, meaning it’s designed to handle the demands of engines that don't use a turbocharger or supercharger. The 4340 forged steel crank and rods are strong choices for performance builds, offering improved durability over cast components. The ICON 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 head volume. The included ARP 8740 bolts for the connecting rods are a solid choice for ensuring the rods stay securely fastened under stress. The plasma-moly file-fit rings give you the flexibility to set your ring gap precisely for your application, which is important for sealing and performance. Finally, the KING XP bearings are designed for high-performance use, providing reliable lubrication and wear resistance for both the main and rod journals.

When putting this assembly together, remember that the piston rings are file-fit, meaning you'll need to gap them to your specific cylinder bore and intended use. This is a standard practice for performance engines to ensure proper sealing and prevent ring flutter at high RPMs. This assembly is intended for racing use and is not CARB approved, so it cannot be shipped to California. Always consult your engine builder or a trusted mechanic for specific installation procedures and recommendations for your build.
