Eagle Chevy LT1 350 1Pc 3.480in Crank 5.700in I-Beam Rods -21cc 4.030in Pistons Rotating Assembly

Eagle has a solid reputation for making well-built performance engine components, and this rotating assembly is a prime example for your Chevy LT1 350. This is a complete package designed to get your engine back to life with improved internals. It includes a 3.480-inch stroke crankshaft, 5.700-inch I-beam connecting rods, and pistons sized at 4.030 inches with a -21cc dish volume. This assembly is a critical step for anyone rebuilding or upgrading their LT1 engine, providing the core rotating parts needed for a strong foundation.

The crankshaft is forged from high-quality steel, offering the strength needed to handle increased power output and demanding use. The I-beam connecting rods are also forged, providing a robust link between the pistons and the crankshaft. These rods are known for their strength-to-weight ratio, making them a popular choice for performance builds. The included pistons are designed with a -21cc dish, which will affect your compression ratio depending on your cylinder head volume. This specific bore size, 4.030 inches, is common for many LT1 350 builds, and Eagle ensures these components work together as a balanced set.

When undertaking an engine rebuild of this caliber, it's important to ensure all components are properly balanced. While this assembly provides the core rotating parts, you'll want to confirm balancing procedures with your machine shop. This kit is intended for performance applications and is not CARB approved, meaning it cannot be shipped to California. Ensure you consult with your engine builder or machine shop to confirm compatibility with your specific build goals and any other necessary components for a complete engine assembly.
