About this part

Product Details

This is a balanced rotating assembly from Eagle, designed for serious performance builds. What you get is a complete package ready to be installed into your Chevy 350 engine. It includes a 3.750-inch forged 4340 crankshaft, 5.700-inch H-beam connecting rods with 7/16-inch ARP 8740 bolts, and 4.030-inch forged 4032 Icon pistons featuring an -18cc inverted dome. This assembly also comes with plasma-moly file-fit piston rings and King XP rod and main bearings, all balanced as a unit for smooth operation.

This rotating assembly is built for demanding use, including racing applications that might involve nitrous or forced induction. The forged 4340 crankshaft and H-beam connecting rods are strong choices for handling increased power and stress. The Icon pistons are forged from 4032 aluminum, a material known for its good thermal expansion properties, and feature an inverted dome design that can be beneficial for compression ratio and combustion chamber shape. The included file-fit piston rings allow for precise gap setting, which is crucial for optimal sealing and performance, especially in high-stress environments. The King XP bearings are a well-regarded option for performance applications, offering good durability and oil clearance.

Because this assembly is balanced from the factory, it simplifies the engine building process and helps ensure a smoother running engine. Remember that this assembly is not CARB approved and cannot be shipped to California. For installation, you'll want to refer to the manufacturer's detailed instructions, as proper assembly and torque specifications are critical for the longevity and performance of these high-performance components.
