About this part

Product Details

This Eagle rotating assembly starts with a 3.750-inch forged 4340 crankshaft, a solid foundation for building a powerful Chevy LT1 350 engine. The forged 4340 steel is known for its strength and durability, making it a reliable choice for demanding applications like racing, nitrous, or forced induction setups. This assembly is designed to handle the extra stress these conditions put on internal engine components.

Paired with the crankshaft are 5.700-inch H-beam connecting rods. These rods are well-built and feature 7/16-inch ARP 8740 bolts, which are a significant upgrade over stock fasteners, ensuring a secure connection under high loads. The assembly also includes 4.000-inch flat-top pistons from Icon, made from forged 4032 aluminum. These pistons have a -5cc dish, which is important for setting your compression ratio depending on your cylinder head choice. They come with plasma-moly file-fit rings, allowing for precise ring gap setting during assembly. To complete the package, King XP rod and main bearings are included, offering robust lubrication and wear resistance for the crankshaft journals.

This is a comprehensive rotating assembly package, ideal for anyone rebuilding or upgrading their Chevy LT1 350 engine for performance use. It's important to note that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations. Always refer to the manufacturer's installation instructions for proper assembly and tuning procedures.
