Eagle Ford 429/460 4.140in Crank 6.800in I-Beam Rods -3cc Flat Top 4.440in Pistons Rotating Assembly

If you're rebuilding the heart of your Ford 429 or 460 engine for street use, this rotating assembly from Eagle is a solid choice. It’s designed to handle pump gas and naturally aspirated setups, making it a practical option for bringing your classic Ford back to life or building a reliable street machine. This assembly includes all the core components you need to get your short block started, ensuring a balanced and well-matched set of parts from a reputable brand.

At the center of this assembly is a 4.140-inch cast crankshaft, built to handle the demands of street driving. Paired with it are 6.800-inch I-beam connecting rods, which are a well-known and reliable design for many performance applications. These rods come equipped with 7/16-inch ARP 8740 bolts, a strong choice for ensuring a secure connection. The pistons are forged SRP units, featuring a -3cc flat top design and a 4.440-inch bore size, which are crucial for achieving the correct compression ratio with your chosen cylinder heads. To complete the package, this assembly includes plasma-moly file-fit piston rings and King rod and main bearings, providing a well-rounded set of components ready for assembly.

When putting this assembly together, remember that the piston rings are file-fit, meaning they need to be gapped to your specific cylinder bore and intended use. This allows for a more precise fit and better sealing. While this assembly is designed for street performance, it's important to note that it is not CARB approved and cannot be shipped to California. Always consult your engine builder or a trusted mechanic for specific assembly and break-in procedures to ensure the longevity of your new engine.
