Eagle Chevy 454 4.250in Crank 6.385in I-Beam Rods 18cc Dome 4.310in Pistons Rotating Assembly

When you're building a serious Chevy 454 engine, especially for naturally-aspirated racing, getting the rotating assembly right is key. This Eagle Pro Street rotating assembly gives you the core components you need to start your build. You'll receive a 4.250-inch forged 4140 crankshaft, a set of 6.385-inch 4340 I-beam connecting rods, and Mahle 4.310-inch forged pistons with an 18cc dome. This assembly is designed to handle the demands of racing applications where every component needs to perform reliably.

The crankshaft is forged from 4140 steel for strength, and the 4340 I-beam connecting rods are paired with 7/16-inch ARP 8740 bolts, known for their durability in high-stress environments. The Mahle pistons are forged from 4032 aluminum, a material chosen for its thermal expansion properties, and feature an 18cc dome to achieve a specific compression ratio. This assembly also includes plasma-moly file-fit piston rings, which allow for precise gap setting to match your engine's bore and desired performance. To complete the package, King XP rod and main bearings are included, offering robust performance for your engine's critical rotating components.

This rotating assembly is intended for racing use and is not CARB approved, meaning it cannot be shipped to California. Ensure you check all local regulations regarding emissions compliance for your build. This kit provides a solid foundation for a high-performance naturally-aspirated 454 engine.
