This Eagle rotating assembly is built for Chevy 350 engines and includes a 1-piece rear main seal crankshaft, I-beam connecting rods, and pistons. It's a well-built package designed to be balanced and ready for installation, simplifying the process of rebuilding or upgrading your engine's core components. The 3.480-inch stroke crankshaft, 5.700-inch connecting rods, and 4.040-inch pistons are selected to work together, forming the heart of your engine's power delivery.

The crankshaft is forged from durable steel and features a 1-piece rear main seal design, which is a common upgrade for many Chevy V8 applications, offering improved sealing over the older 2-piece seal. The 5.700-inch I-beam connecting rods are strong and reliable for performance builds, paired with 4.040-inch pistons that are ready for your chosen compression ratio and ring setup. This assembly comes balanced from Eagle, meaning the critical rotating mass has been precisely weighted to reduce engine vibration and ensure smooth operation right out of the box. This saves significant machine shop time and cost, making it a practical choice for serious engine builders.

When undertaking an engine build of this magnitude, it's crucial to ensure all supporting components are up to the task. This rotating assembly is the foundation, and you'll need to consider matching it with appropriate camshafts, cylinder heads, and a robust block to achieve your desired performance goals. Always refer to the manufacturer's detailed installation instructions and consult with a professional engine builder to ensure proper assembly and break-in procedures are followed for optimal longevity and performance.
