Eagle Chevy LT1350 1Pc 3.480in Crank 5.700in I-Beam Rods -21cc 4.000in Pistons Rotating Assembly

This is the Eagle Chevy LT1350 1-piece rotating assembly, built for LT1 and LS1 style Chevy engines. It's a complete package designed to be the foundation for a performance rebuild or a significant upgrade to your engine's internals. You get a 3.480-inch stroke crankshaft, 5.700-inch I-beam connecting rods, and 4.000-inch pistons with a -21cc dish, all balanced and ready to go.

Eagle has put together a well-built rotating assembly here. The crankshaft is forged from 4340 steel, which is a strong material known for handling the stresses of higher horsepower applications. The I-beam connecting rods are also forged from 4340 steel, and they feature a robust design suitable for performance builds. The pistons are cast aluminum with a -21cc dish, which is important for achieving the correct compression ratio with your cylinder heads. This assembly comes balanced, saving you a significant step and potential cost during your engine build. It's designed to fit 4.000-inch bore blocks, making it a popular choice for many common Chevy V8 displacements.

When you're building an engine, the rotating assembly is critical. It's the heart of the engine, converting the up-and-down motion of the pistons into the rotational force that drives your vehicle. Choosing a quality, balanced assembly like this Eagle unit helps ensure reliability and performance. Remember that this assembly is not CARB approved and cannot be shipped to California. Always consult your engine builder or a trusted mechanic to confirm compatibility with your specific cylinder heads and camshaft to achieve your desired compression ratio and performance goals.
