Eagle Chevy 350 3.750in Crank 6.000in I-Beam Rods -18cc 4.040in Pistons Balanced Assembly

If you're rebuilding a Chevy 350 engine for street use, especially for pump gas and naturally aspirated applications, a balanced rotating assembly like this one from Eagle can save you a lot of time and ensure critical components are matched correctly. This assembly includes a 3.750-inch cast crankshaft, 6.000-inch I-beam connecting rods with 3/8-inch ARP 8740 bolts, and Icon forged 4032 pistons with an -18cc inverted dome. It's all balanced together from the factory, meaning the critical weight matching of the crank, rods, pistons, and bearings is already done for you.

The Icon pistons are designed for a 4.040-inch bore and feature an inverted dome to help achieve a desired compression ratio, especially when paired with specific cylinder heads. They come with plasma-moly standard gap rings, which are a solid choice for street performance. King SI rod and main bearings are included, known for their reliable performance in street applications. This assembly is intended for pump gas and naturally aspirated setups, making it a strong foundation for a refreshed or performance-oriented street engine.

Because this assembly is balanced, it simplifies the engine building process significantly, as the balancing procedure is often one of the more time-consuming and specialized steps. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and assembly procedures.
