If you're building a high-performance Chevy 454 engine for naturally-aspirated racing, this Eagle Pro Street Rotating Assembly is a solid foundation. It bundles together the core components you need to get your engine rotating, all designed to handle the demands of the track. This assembly is specifically put together for the Chevy 454 engine, giving you a direct path to a powerful build.

At the heart of this assembly is a 4.000-inch forged 4340 steel crankshaft, chosen for its strength and durability under stress. Paired with it are 6.135-inch I-beam connecting rods, also made from robust 4340 steel, and they come equipped with 7/16-inch ARP 8740 bolts for a secure connection. The pistons are 4.320-inch ICON forged 2618 aluminum with an 18cc closed chamber dome, designed to work with specific compression ratios. You'll also find plasma-moly file-fit piston rings, which allow for precise gapping to match your engine's needs, and King XP rod and main bearings to ensure smooth operation and proper oil clearance. This combination of well-built components is intended to give you improved performance and reliability for your racing application.

When assembling this rotating assembly, pay close attention to the file-fit nature of the piston rings; proper gapping is crucial for sealing and performance. This assembly is not CARB approved and cannot be shipped to California. Always consult the manufacturer's detailed installation instructions for critical steps like bearing clearance, ring gap, and piston-to-valve clearance to ensure optimal performance and longevity of your engine build.
