Eagle Chevy 350 3.480in Crank 5.700in H-Beam -21cc 4.000in Pistons Rotating Assembly

This Eagle rotating assembly gives you a complete package for rebuilding or upgrading your Chevy 350 engine. Inside this kit, you'll find a 3.480-inch stroke crankshaft, 5.700-inch H-beam connecting rods, and a set of -21cc dish pistons designed for a 4.000-inch bore. This assembly is built to handle more power than a stock setup, making it a solid choice for performance builds where reliability is key.

The crankshaft is forged from high-quality steel, offering a strong foundation for your engine's power delivery. Paired with the robust H-beam connecting rods, which are known for their strength and ability to withstand higher RPMs and increased cylinder pressures, this assembly is well-suited for performance applications. The -21cc dish pistons are designed to work with specific cylinder head volumes to achieve your desired compression ratio, typically around 9.5:1 to 10.5:1 depending on your head choice, which is a popular range for street performance and mild racing engines. Eagle is a well-known name in performance engine components, and this kit reflects their focus on providing durable parts for enthusiasts.

When installing this rotating assembly, proper balancing is crucial for engine longevity and smooth operation. It's recommended to have the entire assembly (crankshaft, connecting rods, pistons, rings, bearings, and harmonic balancer/flexplate) professionally balanced by a reputable machine shop to match your specific engine build and intended use. This attention to detail ensures your engine runs efficiently and reliably for years to come. Please note that this assembly is not CARB approved and cannot be shipped to California.
