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

Eagle is well-known for building solid engine components, and this balanced rotating assembly is a prime example of their work for Chevy 400 engines. If you're building a street-driven vehicle that runs on pump gas and isn't force-fed, this assembly is designed to handle that kind of use. It's a complete package that takes the guesswork out of matching critical rotating parts.

This assembly starts with a 3.750-inch cast crankshaft, paired with 6.000-inch I-beam connecting rods. These rods are secured with 3/8-inch ARP 8740 bolts, which are a strong choice for street applications. Forged Mahle pistons are included, featuring a -5cc flat top design and a 4.165-inch bore size, complete with plasma-moly standard gap rings. To ensure proper bearing performance and longevity, King rod and main bearings are part of the package. This assembly also comes balanced, and includes a damper and flexplate, making it a comprehensive solution for your engine build.

Because this assembly is balanced from the factory, it can save you significant time and expense at the machine shop. It's important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
