Eagle Chevy 350 3.480in Crank 5.700in I-Beam Rods -5cc Flat Top 4.040in Pistons Balanced Assembly

If you're building or rebuilding a Chevy 350 engine for street use, this balanced rotating assembly from Eagle is a solid foundation. It includes a 3.480-inch cast crankshaft, 5.700-inch I-beam connecting rods with 3/8-inch ARP 8740 bolts, and a set of Mahle -5cc flat-top pistons designed for a 4.040-inch bore. This assembly is balanced from the factory, which is a crucial step for engine longevity and smooth operation, especially in street-driven vehicles that see regular use.

The components in this Eagle assembly are chosen for their suitability in pump gas, naturally aspirated street applications. The Mahle pistons are forged from 4032 alloy, known for its good thermal expansion properties, and feature a -5cc dish to help achieve a desired compression ratio with typical cylinder heads. They come with plasma-moly standard gap rings, which are a popular choice for their durability and sealing capabilities. The I-beam connecting rods are strong and well-suited for this type of build, and they are paired with King SI rod and main bearings to ensure proper lubrication and wear resistance for the crankshaft journals.

This assembly is balanced as a complete unit, meaning Eagle has taken the time to match the weights of the rotating components. This reduces the need for excessive balancing during the engine assembly process and helps ensure the engine runs smoothly. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. It's a well-put-together package for someone looking to build a reliable street 350.
