Eagle Chevy 350 3.480in Crank 5.700in I-Beam Rods 5.9cc Dome 4.000in Pistons Rotating Assembly

This Eagle rotating assembly is built for Chevy 350 engines, featuring a 3.480-inch crankshaft, 5.700-inch I-beam connecting rods, and 4.000-inch, 5.9cc dome pistons. It’s a comprehensive package designed to be the heart of a performance engine build, offering a solid foundation for increased power and durability. This assembly is a popular choice for those looking to rebuild or upgrade their small-block Chevy, providing a balanced and matched set of critical internal components.

The crankshaft is forged from 4340 steel, known for its strength and ability to handle higher RPMs and increased stress compared to cast iron. Paired with these are the 5.700-inch I-beam connecting rods, also forged from 4340 steel, which offer a good balance of strength and weight for performance applications. The pistons are 4.000-inch in diameter with a 5.9cc dome, designed to work with common cylinder head volumes to achieve a desired compression ratio, typically around 10.5:1 to 11.0:1 depending on head chamber size. This specific dome shape helps in achieving a good quench and swirl within the combustion chamber, contributing to efficient combustion and power output.

This assembly includes the crankshaft, connecting rods, and pistons, all balanced as a set to reduce engine vibration and ensure smooth operation. While this kit provides the core rotating components, remember that proper assembly requires attention to detail, including correct bearing clearances, ring gap settings, and balancing procedures. It's important to note that this assembly is not CARB approved and cannot be shipped to California. For optimal performance and longevity, consult with your engine builder or refer to Eagle's detailed specifications for installation and setup.
