Eagle Chrysler 360 4.000in Crank 6.123in H-Beam -20.5cc 4.030in Pistons Balanced Assembly

If you're building a high-performance Chrysler 360 engine for racing, especially with nitrous or forced induction, a balanced rotating assembly is a critical starting point. This assembly from Eagle includes a 4.000-inch stroke crankshaft, 6.123-inch H-beam connecting rods, and 4.030-inch pistons with a -20.5cc dish. Having the entire rotating assembly balanced from the factory saves you significant machine shop time and ensures your engine runs smoothly at high RPMs.

Eagle is well-known for making strong components for performance engines. The H-beam connecting rods are a popular choice for their strength and durability under stress, making them suitable for demanding applications. The pistons are designed to work with this specific stroke and rod length, and the -20.5cc dish helps achieve a desired compression ratio when paired with appropriate cylinder heads. This assembly is balanced as a complete unit, which is crucial for preventing vibrations and ensuring the longevity of your engine, especially when pushing it hard.

This balanced rotating assembly is a solid foundation for a serious engine build. Keep in mind that this part is not CARB approved and cannot be shipped to California. Always consult your engine builder or manufacturer's specifications for proper installation and compatibility with other engine components.
