If you're building a naturally-aspirated racing engine for a Chevy 400, this Eagle Pro Street rotating assembly is a solid foundation. It's designed to handle the demands of the track and provides the core components you need to get your engine rotating.

This assembly starts with a 4.000-inch forged 4340 crankshaft, known for its strength and durability under high stress. Paired with it are 6.000-inch I-beam connecting rods made from 4340 steel, which are secured with 7/16-inch ARP 8740 bolts. These rods are a popular choice for performance builds due to their robust construction. The pistons are forged 2618 JE units, featuring a 6.2cc dome and a 4.125-inch bore size, designed to work with the included plasma-moly file-fit rings. To complete the rotating assembly, King XP rod and main bearings are included, offering reliable lubrication and reduced friction for the critical bearing surfaces.

This is a comprehensive package for serious engine builders. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer installation instructions for proper assembly and break-in procedures.
