If you're rebuilding the heart of your Chevy 454 for street use, this balanced rotating assembly from Eagle is a solid foundation. It's designed to handle pump gas and naturally aspirated setups, making it a great choice for a street-driven vehicle that needs a reliable engine core. This assembly takes the guesswork out of matching critical internal components, ensuring they work together harmoniously.

At the core of this assembly is a 4.250-inch cast crankshaft, paired with 6.385-inch I-beam connecting rods. These rods are secured with 7/16-inch ARP 8740 bolts, known for their strength and reliability in performance applications. The pistons are forged 4032 aluminum from Mahle, featuring a -3cc flat top design and a 4.310-inch bore size, which are crucial for achieving the correct compression ratio with your cylinder heads. The assembly also includes plasma-moly file-fit piston rings, allowing for precise gap setting during installation, and King rod and main bearings to ensure smooth operation and proper oil clearance.

This rotating assembly comes balanced from Eagle, which is a significant step that saves you time and money during the engine building process. Balancing is critical for reducing vibration and improving the longevity of your engine, especially at higher RPMs. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and break-in procedures.
