Eagle Chevy 454 4.000in Crank 6.135in H-Beam -3cc Flat Top 4.250in Pistons Balanced Assembly

This is a balanced rotating assembly from Eagle, specifically built for Chevy 454 engines. It includes a forged 4.000-inch crankshaft, 6.135-inch H-beam connecting rods with 7/16-inch ARP 8740 bolts, and Icon 4.250-inch flat-top pistons with a -3cc dish. This assembly is designed for serious performance applications, including those using nitrous or forced induction.

The forged 4340 steel crankshaft is a strong foundation for high-horsepower engines, offering improved durability over cast cranks. The H-beam connecting rods are well-built for handling the stresses of racing, and they come with reliable 7/16-inch ARP 8740 bolts. 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. This assembly also includes plasma-moly file-fit piston rings and King XP rod and main bearings, ensuring a complete and well-matched rotating assembly ready for installation.

This balanced assembly means the rotating components have been precisely weighted and matched at the factory, saving you time and ensuring proper balance for smoother operation and reduced engine wear at high RPMs. Please note that this assembly is not CARB approved and cannot be shipped to California. It also carries a Prop 65 warning.
