Eagle Chevy LT1 350 1Pc 3.480in Crank 5.700in H-Beam -21cc 4.030in Pistons Rotating Assembly

This rotating assembly from Eagle includes a one-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 4.030-inch bore. It's built for Chevy LT1 350 engines, offering a solid foundation for a performance rebuild or upgrade. The one-piece rear main seal design simplifies installation and helps prevent leaks compared to older two-piece seals.

Eagle is known for well-built internal engine components, and this assembly is no exception. The H-beam connecting rods are a strong choice for builds that see more than stock-level stress, offering a good balance of strength and weight. The pistons are designed with a -21cc dish, which will affect your compression ratio depending on the cylinder head volume you pair them with. This assembly is intended for enthusiasts looking to build or significantly upgrade their LT1 350 engine, providing the core rotating components needed to get started.

When planning your build, consider that this assembly is not CARB approved and cannot be shipped to California. You'll also want to ensure your cylinder heads and camshaft are compatible with the intended compression ratio and intended use of your engine. Proper balancing of the rotating assembly is also a critical step for engine longevity and smooth operation, so factor that into your build plan.
