About this part

Product Details

What you get in this balanced rotating assembly is a complete package designed to get your Chevy 454 engine back to life, or ready for a street performance build. It includes a 4.000-inch cast crankshaft, 6.135-inch I-beam connecting rods secured with 7/16-inch ARP 8740 bolts, and forged 4032 Icon pistons with a -3cc flat top dish. This assembly also comes with plasma-moly file-fit piston rings and King SI rod and main bearings, all balanced and ready for installation.

This Eagle Street & Strip rotating assembly is a solid option for pump gas, naturally aspirated street vehicles. The Icon pistons are forged from 4032 aluminum, which offers good thermal expansion characteristics for street use, and the -3cc flat top design helps achieve a desired compression ratio with many common cylinder head combinations. The 6.135-inch I-beam connecting rods are well-suited for this type of build, and the inclusion of ARP 8740 bolts means you have strong fasteners for the rods. The cast crankshaft is a durable choice for street applications, and the entire assembly is balanced to reduce engine vibration and improve overall smoothness.

When you're putting together a street-driven 454, having a balanced rotating assembly like this one saves you a significant amount of time and ensures the critical rotating components are matched. The plasma-moly file-fit rings give you flexibility during installation to achieve a proper seal with your cylinder walls. Remember that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
