Eagle is well-known for building robust engine components, and this Pro Street rotating assembly is a prime example of their commitment to performance. If you're building a naturally-aspirated racing engine for a Chevy 400 application, this assembly is designed to handle the demands of the track. It brings together key components that form the heart of your engine's power delivery system.

At its core is a 3.750-inch forged 4140 crankshaft, designed with 350 main journal size for compatibility. Paired with this are 5.700-inch I-beam connecting rods made from strong 4340 steel, secured with 7/16-inch ARP 8740 bolts for reliable strength under stress. The assembly includes forged 4032 Mahle pistons with a -5cc flat top design and a 4.125-inch bore size, ready for plasma-moly file-fit rings. To ensure smooth operation and durability, King XP rod and main bearings are included, offering solid performance for your build.

This rotating assembly is intended for racing use and is not CARB approved, meaning it cannot be shipped to California. It's a well-built package for those looking to maximize power in a naturally-aspirated setup.
