If you're building a high-performance Chevy 400 engine for naturally-aspirated racing, this Eagle Pro Street rotating assembly is a solid foundation. It bundles together the critical rotating components you need to get your engine build underway, ensuring compatibility and strength for demanding use.

This assembly features a 3.750-inch forged 4340 crankshaft, known for its durability and ability to handle significant stress. Paired with it are 6.000-inch I-beam connecting rods made from the same strong 4340 steel, secured with 7/16-inch ARP 8740 bolts. These ARP bolts are a popular choice for their reliability in high-stress applications.

To complete the package, King XP rod and main bearings are included, offering robust performance for the rotating assembly.
