Eagle Chevy 400 3.750in Crank 6.000in I-Beam Rods -5cc Flat Top 4.185in Pistons Balanced Assembly

Built around a 3.750-inch cast crankshaft, this Eagle rotating assembly is a solid foundation for your Chevy 400 engine build, especially if you're aiming for a street-driven vehicle that runs on pump gas and is naturally aspirated. The 6.000-inch I-beam connecting rods are a well-known choice for their strength and reliability in these applications, and they come equipped with 3/8-inch ARP 8740 bolts, a significant upgrade for ensuring secure rod cap clamping under stress.

The assembly includes forged 4032 Icon pistons, which feature a -5cc flat top design and measure 4.185 inches in diameter. These pistons are paired with plasma-moly file-fit rings, giving you the flexibility to set your ring gap precisely for optimal performance and sealing. King SI rod and main bearings are also included, providing a durable and well-matched interface for the crankshaft and connecting rods. This entire assembly is balanced by Eagle, meaning it's ready to be installed with less balancing work required at your machine shop, saving you time and money.

This balanced rotating assembly is designed for street performance and is a popular choice for engine rebuilds where durability and reliable power on pump gas are key. Please note that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and break-in procedures.
