Eagle Chevy 350 3.750in Crank 5.700in I-Beam Rods -5cc Flat Top 4.060in Pistons Balanced Assembly

If you're rebuilding the heart of your Chevy 350 for street use, a balanced rotating assembly like this one from Eagle is a solid foundation. This assembly is designed to handle pump gas and naturally aspirated setups, making it a great choice for daily drivers or weekend cruisers that need more grunt. Getting the rotating assembly balanced from the factory saves you a significant step and ensures everything spins true right out of the box.

Eagle has put together a well-built package here. It starts with a 3.750-inch cast crankshaft, paired with 5.700-inch I-beam connecting rods secured by 3/8-inch ARP 8740 bolts. For the pistons, you get forged 4032 Icon flat-top pistons with a -5cc dish, designed for a 4.060-inch bore. These come with plasma-moly standard gap rings, which are known for good sealing. To top it off, the assembly includes King SI rod and main bearings, providing reliable lubrication for the critical journals.

This assembly is balanced, which is a crucial step for engine longevity and smooth operation. 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.
