About this part

Product Details

If you're building a high-performance Chevy 454 for serious racing, a balanced rotating assembly is the foundation you need. This assembly from Eagle is designed to handle the demands of competition, including applications using nitrous or forced induction. It brings together key components that work in harmony to create a strong, reliable powerhouse for your build.

At the heart of this assembly is a forged 4340 crankshaft with a 4.250-inch stroke, providing the base for increased displacement and power. Paired with it are 6.385-inch H-beam connecting rods, known for their strength and ability to withstand high RPMs and significant cylinder pressures. These rods are secured with 7/16-inch ARP 8740 bolts, a popular choice for their reliability in demanding builds. The pistons are forged Mahle 4.320-inch units with a 43cc dome, designed for performance and compatibility with the included components. They come with plasma-moly file-fit rings, allowing for precise gap setting to optimize performance and sealing. To ensure smooth operation and durability, the assembly includes King XP rod and main bearings, which offer improved wear resistance and load-carrying capacity.

This assembly comes balanced from the factory, saving you a significant step and ensuring proper weight distribution for reduced vibration and increased longevity. 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 get the most out of this high-performance rotating assembly.
