Eagle is well-known for building strong rotating assemblies that can handle serious power, and this competition-ready package for the Chevy LT1 350 is no exception. If you're building a high-performance engine for racing, nitrous, or forced induction, this assembly gives you the core components you need to get started. It’s designed to be a robust foundation for builds that demand reliability under extreme conditions.

At the heart of this assembly is a 3.750-inch forged 4340 crankshaft, chosen for its strength and durability. Paired with this are 5.700-inch H-beam connecting rods, which are a popular choice for their solid construction and ability to withstand high loads. These rods come equipped with 7/16-inch ARP 8740 bolts, a name trusted for their quality and reliability in high-stress applications. The pistons are forged 4032 aluminum from Mahle, featuring a -5cc flat top design and a 4.060-inch bore size, ready to be paired with your chosen cylinder heads. They come with plasma-moly file-fit rings, allowing for precise gap setting to optimize performance and sealing. To complete the package, King XP rod and main bearings are included, offering excellent wear resistance and smooth operation for the crankshaft.

This rotating assembly is a comprehensive starting point for a powerful LT1 engine build. Please note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
