Eagle Chevy 350 3.480in Crank 5.700in I-Beam Rods -3.7cc Flat Top 4.040in Pistons Balanced Assembly

Eagle is well-known for making strong internal engine components, and this balanced rotating assembly is a prime example for your Chevy 350 build. It’s designed for street vehicles running on pump gas and naturally aspirated setups, making it a solid choice for many common engine projects. This assembly gives you all the core rotating parts you need to get your engine back together and running strong.

Inside this assembly, you'll find a 3.480-inch cast crankshaft, paired with 5.700-inch I-beam connecting rods. These rods come equipped with 3/8-inch ARP 8740 bolts, a detail that shows Eagle's attention to making these parts reliable for street use. The pistons are forged 4032 aluminum from ICON, featuring a -3.7cc flat top design with a 4.040-inch bore size. They also include plasma-moly standard gap rings, which help ensure a good seal and efficient combustion. To top it off, the assembly comes with King SI rod and main bearings, ready to be installed.

This is a balanced assembly, meaning the crankshaft, rods, pistons, rings, and bearings have been balanced together at the factory. This step is crucial for reducing engine vibration and ensuring smoother operation, especially at higher RPMs. Please note that this assembly 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.
