Eagle Chevy 400 3.750in Crank 5.700in I-Beam Rods -18cc 4.165in Pistons Balanced Assembly

This is a balanced rotating assembly from Eagle, specifically designed for Chevy 400 applications. It includes a 3.750-inch crankshaft, 5.700-inch I-beam connecting rods, and -18cc 4.165-inch pistons. This assembly is a crucial component for anyone rebuilding or upgrading their engine, providing a solid foundation for significant power gains.

Eagle has put together a well-built package here. The crankshaft is forged for strength, ready to handle the stresses of a performance engine. The I-beam connecting rods are also forged, offering a strong and reliable link between the pistons and the crankshaft. These rods are a popular choice for builds aiming for substantial horsepower. The included pistons are designed with a -18cc dish, which is important for achieving specific compression ratios when paired with the right cylinder heads and head gasket thickness. This assembly comes balanced from Eagle, saving you a significant step and potential cost in the engine building process. Balancing is critical for smooth operation and longevity, especially at higher RPMs.

When undertaking an engine build of this caliber, it's important to ensure all supporting components are up to the task. This includes proper block preparation, quality bearings, and a suitable camshaft. Because this assembly is not CARB approved, it cannot be shipped to California. Always consult your engine builder or a trusted mechanic to confirm compatibility with your specific build goals and local emissions regulations.
