Eagle Chevy 400 3.750in Crank 5.700in I-Beam Rods -16cc 4.185in Pistons Balanced Assembly

This is a balanced rotating assembly from Eagle, specifically designed for Chevy 400 engines. It includes a 3.750-inch cast crankshaft, 5.700-inch I-beam connecting rods with 3/8-inch ARP 8740 bolts, and forged 4032 DSS pistons featuring a -16cc inverted dome and a 4.185-inch bore. The assembly also comes with plasma-moly file-fit rings and King SI rod and main bearings, all balanced and ready for installation.

This rotating assembly is a solid choice for street-driven vehicles that run on pump gas and are naturally aspirated. The forged 4032 pistons are well-suited for these conditions, offering good durability and performance. The inclusion of ARP bolts for the connecting rods means you're getting strong, reliable fasteners that are known for their quality. The plasma-moly file-fit rings allow for precise gap adjustment, which is important for proper sealing and performance in a performance street engine. King bearings are also a well-known name in engine building, providing dependable lubrication and wear resistance for both the rods and main journals.

Because this assembly is balanced from the factory, it saves you a significant step in the engine building process. This is particularly helpful for a street build where time and precision are key. Keep in mind 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 to ensure the longevity of your new engine components.
