About this part

Product Details

This Eagle Competition Rotating Assembly starts with a forged 4340 steel crankshaft featuring a 3.750-inch stroke, a solid foundation for building a powerful Chevy 350 engine. The assembly includes 5.700-inch H-beam connecting rods, known for their strength and reliability under stress, secured with 7/16-inch ARP 8740 bolts. These components are crucial for handling the increased cylinder pressures found in performance applications.

The pistons are forged 4032 aluminum from Icon, designed with a -5cc flat top dish and a 4.060-inch bore size, which is standard for many Chevy 350 builds. They come complete with plasma-moly file-fit piston rings, allowing for precise gap setting to optimize sealing and performance. This attention to detail in the ring setup is vital for maximizing compression and minimizing blow-by, especially when using nitrous or forced induction.

To ensure smooth operation and proper oil clearance right out of the box, the assembly is balanced and includes King XP series rod and main bearings. This balanced rotating assembly is engineered for demanding use, including all forms of racing, nitrous oxide systems, and forced induction setups. Please note that this assembly is not CARB approved and cannot be shipped to California. It also carries a Prop 65 warning.
