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 components you need to get your engine's bottom end ready for serious work. This assembly is designed to handle the demands of racing, providing a well-built core for your project.

At the heart of this assembly is a forged 4340 crankshaft with a 3.750-inch stroke, paired with 6.000-inch I-beam connecting rods also made from strong 4340 steel. These rods are secured with 7/16-inch ARP 8740 bolts, known for their reliability under stress. The pistons are forged 4032 aluminum from ICON, featuring a -5cc flat top design and a 4.185-inch bore, which work well with the crank and rod combination for a specific displacement. The assembly also includes plasma-moly file-fit piston rings, allowing for precise gap setting to match your engine's bore and intended use, and King XP rod and main bearings to ensure smooth rotation and proper oil clearance.

This rotating assembly is a comprehensive package for builders looking for robust components for their Chevy 400. Please note that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and balancing procedures.
