Eagle Chevy LT1 350 1Pc 3.480in Crank 5.700in I-Beam Rods -21cc 4.000in Pistons Rotating Assembly

Eagle Specialty Products has a solid reputation for making well-built performance engine components, and this rotating assembly for Chevy LT1 350 engines is no exception. If you're rebuilding your top end or looking to get more out of your small-block Chevy, this kit is designed to handle the power. It includes a 3.480-inch stroke crankshaft, 5.700-inch I-beam connecting rods, and 4.000-inch pistons with a -21cc dish volume, which will result in a specific compression ratio depending on your cylinder heads and block deck height.

The crankshaft is forged from 4340 steel, a strong material known for its durability under high stress, making it a reliable foundation for your engine build. The I-beam connecting rods are also forged from 4340 steel, offering a good balance of strength and weight for performance applications. The included pistons are cast aluminum, a common choice for performance builds that balances weight savings with durability. This assembly is balanced, meaning the crankshaft, rods, and pistons are weighted and machined to work together smoothly, reducing vibration and improving overall engine life. This is a critical step for any performance engine build, ensuring the rotating assembly runs true and true.

This rotating assembly is a significant upgrade for anyone looking to build a powerful and reliable LT1 engine. 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 balancing procedures, and consult with a professional engine builder to ensure compatibility with your specific cylinder heads and desired compression ratio.
