Eagle Chevy 454 4.250in Crank 6.385in I-Beam Rods -3cc Flat Top 4.350in Pistons Balanced Assembly

Eagle has a solid reputation for making well-built performance engine components, and this balanced rotating assembly is a prime example for your Chevy 454 build. If you're putting together a street-driven vehicle that runs on pump gas and doesn't use a supercharger or turbo, this assembly is designed to handle that kind of work. It's a complete package that takes the guesswork out of matching critical rotating 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 4.350-inch bore size. They come with plasma-moly file-fit rings, which allow for precise gap setting to match your specific engine build. To top it off, the assembly includes King SI rod and main bearings, providing solid lubrication and wear protection for these high-performance components.

This assembly is balanced from the factory, meaning Eagle has taken the time to ensure the rotating mass is properly weighted. This is crucial for reducing engine vibration and improving overall smoothness and longevity, especially in a street application. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. It's a robust option for anyone looking to build a reliable, naturally aspirated 454 engine for street use.
