Eagle Chevy 350 3.480in Crank 5.700in H-Beam -21cc 4.060in Pistons Rotating Assembly

Eagle is a well-known name in the performance engine parts world, and this rotating assembly is built to handle serious power for your Chevy 350. If you're rebuilding your engine's core or looking to build a high-performance powerplant, this assembly gives you the essential components to get started. It includes a 3.480-inch stroke crankshaft, 5.700-inch H-beam connecting rods, and pistons designed for a 4.060-inch bore with a -21cc dish volume. This combination is a popular choice for building a robust and powerful small-block Chevy engine.

The heart of this assembly is the crankshaft, forged from strong steel to withstand the stresses of high RPM and increased cylinder pressures. Paired with the H-beam connecting rods, which offer a strong and reliable link between the pistons and the crankshaft, this setup is designed for durability. The included pistons are forged and feature a -21cc dish, which is a common volume for achieving specific compression ratios when paired with appropriate cylinder heads and head gaskets on a 4.060-inch bore. This assembly is a significant step towards building a performance engine that can handle more aggressive camshafts and higher boost levels.

This rotating assembly is a critical part of your engine's foundation. While it doesn't include bearings, rings, or a balancer, it provides the core rotating mass. Ensure you have the correct specifications for your build, including piston ring groove sizes and wrist pin diameter, to select compatible components. Please note this assembly is not CARB approved and cannot be shipped to California.
