Eagle Chevy 350 1Pc 3.480in Crank 5.700in I-Beam Rods 5.9cc Dome 4.040in Pistons Rotating Assembly

Eagle is well-known for making strong internal engine components, and this rotating assembly is a prime example of their work for Chevy 350 engines. If you're building or rebuilding a performance small-block Chevy, this kit gives you the core rotating parts you need to get started. It includes a 1-piece rear main seal crankshaft with a 3.480-inch stroke, paired with 5.700-inch I-beam connecting rods. The pistons are designed with a 5.9cc dome and a 4.040-inch bore size, which is a common size for many 350 builds and allows for potential overboring if needed.

This assembly is designed to be a solid foundation for a performance engine. The I-beam connecting rods are a popular choice for their strength and reliability in many street and strip applications. The 1-piece crankshaft simplifies installation compared to older 2-piece rear main seal designs, and it's a common upgrade for many Chevy V8s. Eagle balances these rotating assemblies to reduce vibration and ensure smooth operation, which is crucial for engine longevity, especially when you're pushing more power.

When considering this rotating assembly, remember it's intended for performance applications and may require other supporting modifications to your engine. This includes proper balancing with your chosen flywheel or flexplate, and ensuring your block is machined to accept the 4.040-inch pistons. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always consult with your engine builder or a trusted mechanic to ensure this assembly is the right fit for your specific build goals and to confirm all necessary supporting components are accounted for.
