Eagle Chevy 427 3.766in Crank 6.135in I-Beam Rods 41cc Dome 4.320in Pistons Balanced Assembly

This balanced rotating assembly from Eagle is built for naturally-aspirated racing applications, specifically for Chevy 427 engines. What you get in this package is a complete rotating assembly ready for installation. It includes a forged 4340 crankshaft with a 3.766-inch stroke, a set of 6.135-inch 4340 I-beam connecting rods fitted with 7/16-inch ARP 8740 bolts, and forged 4032 Icon pistons featuring a 41cc dome and a 4.320-inch bore size. To complete the assembly, it comes with plasma-moly file-fit piston rings and King XP rod and main bearings.

The use of forged 4340 steel for both the crankshaft and connecting rods means these components are well-built to handle the stresses of racing. The I-beam design of the rods is a popular choice for performance builds, and the inclusion of ARP 8740 bolts ensures a strong connection. The Icon pistons are forged from 4032 aluminum, known for its good thermal expansion properties, and the 41cc dome shape is designed to achieve a specific compression ratio when paired with the crankshaft and your cylinder heads. The file-fit plasma-moly rings allow for precise gapping to match your engine's bore and intended use, while the King XP bearings are chosen for their performance capabilities.

This assembly is balanced from the factory, which is a critical step for engine longevity and smooth operation, especially in high-RPM applications. It's important to note 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 optimal performance and durability.
