Eagle Chevy 454 4.000in Crank 6.135in I-Beam Rods 27cc Dome 4.250in Pistons Rotating Assembly

Starting with a 4.000-inch forged 4340 steel crankshaft, this Eagle Pro Street rotating assembly is built for serious performance in naturally-aspirated racing applications. The crankshaft is paired with 6.135-inch long I-beam connecting rods, also forged from 4340 steel. These rods are secured with robust 7/16-inch ARP 8740 bolts, ensuring they can handle the stresses of high-RPM operation.

The assembly includes 4.250-inch forged 2618 aluminum pistons from ICON, featuring a 27cc closed chamber dome design that's optimized for specific compression ratios. These pistons come with plasma-moly file-fit rings, allowing for precise gap setting to match your engine's bore and intended use. To complete the package, King XP series rod and main bearings are included, offering reliable lubrication and wear resistance for the critical rotating components.

This rotating assembly is a well-built foundation for a performance Chevy 454 engine. 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.
