Eagle has built a reputation for well-built performance engine components, and this balanced rotating assembly is a prime example for your Chevy 400 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 use.

Inside this balanced assembly, you'll find a 3.750-inch cast crankshaft ready to be the heart of your engine. It's paired with 5.700-inch I-beam connecting rods, which are a solid choice for street applications. These rods come equipped with 3/8-inch ARP 8740 bolts, known for their strength and reliability in keeping your rotating assembly together under load. The pistons are forged 4032 aluminum from ICON, featuring a -5cc flat top design and a 4.155-inch bore size, ready to be filed to fit your specific needs. This assembly also includes plasma-moly file-fit piston rings, giving you the flexibility to achieve a precise seal in your cylinders. To top it off, it comes with KING SI rod and main bearings, which are well-regarded for their performance in street and strip applications.

This assembly is balanced, which is a crucial step for smooth engine operation and longevity. It's important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
