Eagle Chevy 400 3.750in Crank 5.700in I-Beam Rods -16cc 4.165in Pistons Balanced Assembly

This balanced rotating assembly from Eagle is built for Chevy 400 engines, specifically for street applications using pump gas and naturally aspirated setups. What you get in this package is a 3.750-inch cast crankshaft, a set of 5.700-inch I-beam connecting rods equipped with 3/8-inch ARP 8740 bolts, and forged 4032 DSS pistons featuring a -16cc inverted dome design. It also includes plasma-moly file-fit piston rings and King SI rod and main bearings to get your engine rebuild started right.

The components in this assembly are chosen for durability and performance on the street. The forged 4032 pistons are well-suited for the thermal demands of pump gas engines, and the -16cc inverted dome shape helps achieve a desired compression ratio. The I-beam connecting rods are strong and reliable for typical street driving, and they come with ARP 8740 bolts, known for their robust clamping force. The plasma-moly file-fit rings allow for precise cylinder wall sealing, which is crucial for good compression and oil control. King SI bearings are included to ensure proper lubrication and wear protection for the crankshaft and connecting rod journals.

This assembly is balanced from the factory, which is a significant time and labor saver during your engine build. Balancing reduces vibration and improves the overall smoothness and longevity of your engine. 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.
