Eagle Chrysler 360 4.000in Crank 6.123in I-Beam Rods -5cc Flat Top 4.030in Pistons Balanced Assembly

What you get in this balanced rotating assembly is a complete package ready to build a strong Chrysler 360 engine. It includes a forged 4340 crankshaft with a 4.000-inch stroke, 6.123-inch I-beam connecting rods fitted with 3/8-inch ARP 8740 bolts, and Mahle forged 4032 pistons. These pistons are flat-top with a -5cc dish and are sized for a 4.030-inch bore. The assembly also comes with plasma-moly file-fit piston rings and King XP rod and main bearings.

This assembly is balanced from the factory, which is a critical step for any performance engine build. It's designed for naturally-aspirated racing applications, meaning it's built to handle the demands of high-RPM operation without forced induction. The use of a forged 4340 crankshaft and I-beam connecting rods signifies a well-built foundation capable of handling increased power output compared to stock cast components. The Mahle pistons are a popular choice for their durability and performance characteristics, and the inclusion of ARP bolts means you're getting strong, reliable fasteners for the connecting rods.

When installing this rotating assembly, remember that the piston rings are file-fit, meaning they need to be gapped to your specific cylinder bore and intended use. This allows for precise control over ring seal and blow-by. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions for proper assembly and break-in procedures to ensure the longevity and performance of your new engine build.
