If you're building a naturally aspirated 454 big block Chevy for racing, a balanced rotating assembly like this one from Eagle is a solid foundation. This assembly includes all the key components you need to get your engine's bottom end put together, all balanced as a complete unit to ensure smooth operation and reduce vibration. It's designed to handle the demands of racing, giving you confidence when you put the pedal down.

At the heart of this assembly is a forged 4340 steel crankshaft with a 4.000-inch stroke, paired with strong 6.135-inch I-beam connecting rods made from the same 4340 material. These rods are secured with 7/16-inch ARP 8740 bolts, known for their reliability in high-stress applications. The pistons are forged 2618 aluminum from ICON, featuring a 43cc dome and a 4.350-inch bore size, which works with the included plasma-moly file-fit rings. Topping it off, King XP rod and main bearings are included, offering excellent wear resistance and performance.

This assembly comes balanced from the factory, saving you a significant step and ensuring your engine's rotating mass is properly weighted. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. It's a well-built package for those serious about their racing engine build.
