About this part

Product Details

This is a balanced rotating assembly from Eagle, specifically built for Chevy 454 engines. It includes a forged 4340 crankshaft with a 4.250-inch stroke, 6.385-inch H-beam connecting rods secured with 7/16-inch ARP 8740 bolts, and 4.350-inch, 23cc dome forged pistons from Icon. This assembly is designed for serious performance applications, including racing, and comes with plasma-moly file-fit rings and King XP rod and main bearings.

The forged 4340 steel crankshaft is a strong foundation for high-horsepower engines, offering improved durability over cast cranks. The H-beam connecting rods are well-built for handling the stresses of racing, and the ARP bolts ensure a secure connection. Icon's 4032 forged aluminum pistons are designed for high-performance use, with a 23cc dome that contributes to compression ratios suitable for boosted or nitrous applications. The plasma-moly file-fit rings allow for precise gap setting, which is crucial for optimal sealing and performance, especially in demanding conditions. King XP bearings are included to ensure smooth operation and longevity for both the main and rod journals.

This assembly is balanced from the factory, which is a critical step for high-RPM operation, reducing vibration and improving overall engine smoothness and reliability. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures to ensure the longevity and performance of your engine build.
