If you're building a serious performance engine for your Chevy 454, this balanced rotating assembly from Eagle is a solid foundation. It's designed for naturally-aspirated racing applications, meaning it's built to handle the demands of high RPM and significant power output without the complexities of forced induction. This assembly includes all the core components you need to get your engine's bottom end rebuilt and ready for serious work.

At the heart of this assembly is a forged 4140 crankshaft with a 4.250-inch stroke, providing the foundation for increased displacement and torque. Paired with this are 6.385-inch I-beam connecting rods made from strong 4340 steel, which are secured with 7/16-inch ARP 8740 bolts for reliable clamping force under stress. The pistons are forged 4032 aluminum from Mahle, featuring an 18cc dome and a 4.350-inch bore size, designed to work with the crank and rods for optimal compression and performance. This assembly also comes with plasma-moly file-fit piston rings, allowing for precise ring gap adjustment to match your specific build, and King XP rod and main bearings to ensure smooth rotation and durability.

This assembly comes balanced from the factory, saving you a significant step and ensuring your engine runs smoothly and efficiently. It's important to note that this assembly is not CARB approved and cannot be shipped to California.
