Eagle Chevy LT1 350 1Pc 3.480in Crank 5.700in H-Beam -21cc 4.060in Pistons Rotating Assembly

This rotating assembly from Eagle includes a 1-piece rear main seal crankshaft with a 3.480-inch stroke, 5.700-inch H-beam connecting rods, and -21cc dish pistons designed for a 4.060-inch bore. It's built for Chevy LT1 350 engines and is a solid foundation for a performance rebuild or stroker build.

The H-beam connecting rods are known for their strength and rigidity, making them a popular choice for builds that see higher RPMs or more aggressive use than stock. The crankshaft features a 1-piece rear main seal design, which is a common upgrade for many Chevy V8s to prevent leaks. The included pistons are a -21cc dish style, which will affect your compression ratio depending on the cylinder head volume you pair them with. This assembly is designed to work with a 4.060-inch bore, common in many LT1 and related small-block Chevy applications.

When planning your build, consider that this assembly is not CARB approved and cannot be shipped to California. You'll want to ensure your chosen cylinder heads, camshaft, and balancing procedures are compatible with these components to achieve your desired performance and reliability. Proper balancing is crucial for any rotating assembly to ensure smooth operation and longevity.
