If you're building a naturally-aspirated racing engine for your Chevy 350, this balanced rotating assembly from Eagle is a solid option. It's designed to handle the demands of performance builds where every component needs to work together reliably. This assembly includes all the core rotating parts, balanced and ready for installation, saving you time and ensuring proper weight distribution for smoother operation and reduced vibration.

At the heart of this assembly is a forged 4140 steel crankshaft with a 3.480-inch stroke, providing the foundation for increased displacement and power. Paired with this are 6.000-inch long 4340 I-beam connecting rods, known for their strength and durability in performance applications. These rods are secured with 7/16-inch ARP 8740 bolts, a name you can trust for high-strength fasteners. The pistons are forged 4032 aluminum from Icon, featuring a -3.7cc flat top design that works with a 4.040-inch bore size, and they come with plasma-moly standard gap rings for good sealing. To complete the package, King XP rod and main bearings are included, offering robust wear resistance and proper oil clearance for the crankshaft.

This assembly is balanced from the factory, which is crucial for high-RPM engine operation. 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 the longevity of your new engine build.
