Product Details

If you're building a street-driven Chevy 454 that runs on pump gas and doesn't use forced induction, this balanced rotating assembly from Eagle is a solid choice. It's designed to handle the demands of a naturally aspirated engine, giving you a strong foundation for your build. This assembly includes all the key components you need to get your short block put together, saving you time and ensuring compatibility between parts.

At the heart 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 4.320-inch bore size. They come with plasma-moly file-fit rings, which allow for precise gap setting to match your engine's bore and intended use. King SI rod and main bearings are included to ensure smooth rotation and proper oil clearance.

This assembly comes balanced from the factory, which is a critical step for any performance engine build. Balancing reduces vibration, leading to a smoother running engine, less stress on components, and potentially improved longevity. This kit is intended for street applications and is not CARB approved, meaning it cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
