Eagle Chevy 454 1Pc 4.000in Crank 6.135in I-Beam Rods 18.3cc 4.350in Pistons Balanced Assembly

If you're rebuilding a Chevy 454 for street use with pump gas and no power adders, this balanced rotating assembly from Eagle is a solid foundation. It includes a 4.000-inch cast crankshaft, 6.135-inch I-beam connecting rods with ARP 7/16-inch bolts, and 4.350-inch Icon pistons designed for an 18.3cc closed chamber dome. This assembly is balanced from the factory, saving you a significant step in the engine building process.

The Icon pistons are forged from 4032 aluminum, which offers good thermal expansion characteristics for street applications, and they come with plasma-moly file-fit rings. The connecting rods are well-built I-beams, a popular choice for many street performance builds. King SI rod and main bearings are included, providing reliable lubrication for the rotating assembly. This setup is specifically intended for naturally aspirated, pump gas applications, making it a straightforward choice for many street rod or muscle car projects.

When installing this assembly, remember to follow proper engine building procedures, including checking bearing clearances and ensuring all components are clean and properly lubricated. This balanced assembly is designed to simplify the critical balancing step for your engine build. Please note that this assembly is not CARB approved and cannot be shipped to California.
