Product Details
This Eagle rotating assembly starts with a 3.750-inch stroke crankshaft, forged from strong 4340 steel. This material choice is key for handling the stresses of a performance engine build. It's paired with 5.700-inch long H-beam connecting rods, also forged from 4340 steel, which are well-known for their strength and ability to handle higher RPMs and increased cylinder pressures compared to lighter duty rods. The assembly includes 4.030-inch bore pistons, designed to work with the crankshaft and rods to form a complete, balanced rotating assembly ready for your Chevy 350 engine.
The H-beam design of the connecting rods offers a solid balance of strength and weight, making them a popular choice for builds that see regular track use or aggressive street driving. The crankshaft features a 3.750-inch stroke, which, when combined with the 4.030-inch bore pistons, helps to increase the engine's displacement, leading to more power potential. Eagle has a solid reputation for producing well-built engine components, and this rotating assembly is no exception, offering a strong foundation for a rebuilt or performance-oriented Chevy 350.
This assembly is designed as a complete package, simplifying the process of sourcing individual components for your engine build. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always consult your engine builder or a qualified mechanic to ensure this rotating assembly meets the specific requirements and goals of your project.
