About this part

Product Details

Starting with a forged 4340 steel crankshaft with a 4.000-inch stroke is key for building a strong Chevy 454 engine. This balanced rotating assembly from Eagle is designed for naturally-aspirated racing applications, giving you a solid foundation for performance builds. The 4340 I-beam connecting rods measure 6.135 inches long and come equipped with 7/16-inch ARP 8740 bolts, known for their strength and reliability under stress.

The assembly includes Icon 4.310-inch flat-top pistons made from forged 4032 aluminum, featuring a -3cc dish to help achieve your desired compression ratio. These pistons are paired with plasma-moly file-fit rings, allowing for precise gap setting to match your engine's bore and intended use. Forged pistons are chosen for their durability and ability to withstand higher cylinder pressures compared to cast pistons, making them a popular choice for performance builds.

To ensure proper bearing performance and longevity, this assembly comes complete with King XP series rod and main bearings. These bearings are designed to handle the increased loads and temperatures found in performance engines. The entire rotating assembly is balanced by Eagle, which is a critical step to reduce engine vibration and improve overall smoothness and durability. Please note that this assembly is not CARB approved and cannot be shipped to California.
