Eagle Chevy 400 3.750in Crank 6.000in I-Beam Rods -5cc Flat Top 4.165in Pistons Rotating Assembly

This Eagle Pro Street rotating assembly is built for Chevy 400 engines, specifically for naturally-aspirated racing applications. It's a well-built package designed to handle the demands of performance builds where every component needs to work together reliably. If you're putting together a serious street or strip engine, this assembly gives you a solid foundation.

At the heart of this assembly is a 3.750-inch forged 4340 crankshaft, known for its strength and durability under high stress. Paired with it are 6.000-inch I-beam connecting rods, also made from robust 4340 steel. These rods are secured with 7/16-inch ARP 8740 bolts, a name you can trust for holding power. The pistons are forged 4032 aluminum from Mahle, featuring a -5cc flat top design and measuring 4.165 inches in diameter. They come with plasma-moly file-fit rings, which allow for precise gap setting to match your engine's bore and intended use, helping to ensure good sealing and performance. To complete the package, King XP rod and main bearings are included, offering excellent wear resistance and performance for your build.

This assembly is intended for performance use and is not CARB approved, meaning it cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures to ensure the longevity and performance of your engine.
