Eagle Chevy 427/454 Balanced Rotating Assembly

This Eagle Street & Strip Balanced Rotating Assembly gives you a solid foundation for your Chevy 427 or 454 engine build, especially if you're aiming for a pump gas, naturally aspirated street application. What you get in this kit is a fully balanced rotating assembly, meaning the crankshaft, pistons, connecting rods, and rings are all matched and weighted to work together smoothly right out of the box. This saves you a significant step and ensures better engine balance from the start.

Inside this assembly, you'll find a 4.250-inch cast crankshaft ready to handle the demands of street driving. It's paired with 6.385-inch I-beam connecting rods, which are strong and reliable for this type of build. These rods use 7/16-inch ARP 8740 bolts, known for their strength and ability to hold tight under stress. The pistons are forged 4032 aluminum with an 18cc dome, designed for a 4.280-inch bore, and come with plasma-moly file-fit rings. This setup is designed to work well with pump gas and naturally aspirated configurations. To complete the package, Eagle includes King SI rod and main bearings for proper lubrication and wear protection, a Pioneer damper to control torsional vibrations, and a 168-tooth flexplate for automatic transmission applications.

This assembly is a well-built option for someone looking to rebuild or upgrade their classic Chevy V8. Keep in mind that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and torque specifications.
