When you're rebuilding the heart of your Chevy 350, this balanced rotating assembly from Eagle is a solid choice. What you get in this package is a complete rotating assembly ready for installation. It includes a 1-piece rear main seal crankshaft with a 3.480-inch stroke, 5.700-inch I-beam connecting rods, and pistons sized at 4.030 inches. It also comes with a 153-tooth flywheel and is factory balanced, meaning it's ready to go without needing additional balancing work before assembly. This is designed for street and strip applications, offering a good foundation for a performance build.

Eagle has put together a well-built assembly here, focusing on components that work well together. The I-beam connecting rods are a strong choice for many performance builds, offering a good balance of strength and weight. The 3.480-inch stroke crankshaft is a common and effective choice for increasing displacement in a Chevy 350, and the 4.030-inch pistons are standard for a .030 overbore. Having the assembly factory balanced by Eagle saves you a significant step and potential cost in your engine build. This means the critical rotating components—crankshaft, connecting rods, pistons, wrist pins, and bearings—have been precisely weighted and balanced to minimize vibration and ensure smooth operation once installed in your engine block.

This assembly is intended for a 1-piece rear main seal engine block. It's important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and torque specifications to ensure the longevity and performance of your new engine.
