About this part

Product Details

This Eagle Competition Rotating Assembly starts with a forged 4340 steel crankshaft featuring a 3.480-inch stroke, a solid foundation for building a powerful Chevy 350 engine. It's designed to handle the demands of racing, including the extra stress from nitrous and forced induction setups. The assembly includes 5.700-inch H-beam connecting rods, known for their strength and reliability under high loads, secured with 7/16-inch ARP 8740 bolts. These components are crucial for ensuring the engine can withstand aggressive driving and high RPMs without failure.

Complementing the crank and rods are Icon forged 4032 aluminum pistons. These pistons have a -3.7cc flat top dish and are sized for a 4.030-inch bore, which is a common size for many Chevy 350 builds. They come with plasma-moly standard gap rings, designed for good sealing and durability in performance applications. The assembly also includes King XP rod and main bearings, which offer improved lubrication and wear resistance, vital for keeping critical rotating components running smoothly under stress. This entire assembly is balanced from the factory, saving you a significant step and ensuring smoother operation right out of the box.

This balanced rotating assembly is a well-built package for those looking to build a performance-oriented Chevy 350. Please note that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations. Always refer to manufacturer instructions for proper installation and any additional components required for your specific build.
