Eagle Chevy 350 3.480in Crank 5.700in I-Beam Rods -21cc 4.030in Pistons Rotating Assembly

This Eagle rotating assembly starts with a 3.480-inch stroke crankshaft, forged from 4340 steel for strength. It’s paired with 5.700-inch I-beam connecting rods, also forged from 4340 steel, featuring a robust design suitable for performance builds. The assembly includes pistons designed for a 4.030-inch bore with a -21cc dish, which helps achieve a specific compression ratio depending on your cylinder heads and block deck height.

This is a well-built rotating assembly designed for Chevy 350 engines. The 4340 steel construction of both the crankshaft and connecting rods means they can handle increased cylinder pressures and RPMs often found in modified engines. The I-beam rod design is a popular choice for its balance of strength and weight, making it a solid option for street performance or mild racing applications. The included pistons are lightweight and designed to work with the crankshaft and rods to form a balanced rotating assembly, which is crucial for engine longevity and smooth operation at higher speeds.

When rebuilding or upgrading your Chevy 350, a balanced rotating assembly like this one is a critical component. It ensures that the forces within the engine are managed effectively, reducing vibration and wear. This assembly is intended for use in performance applications and requires careful consideration of other engine components, such as camshaft selection, cylinder heads, and tuning, to achieve optimal results. Please note that this assembly is not CARB approved and cannot be shipped to California.
