About this part

Product Details

This Eagle rotating assembly is built around a 4.000-inch cast crankshaft, providing the foundation for a robust Chevy 396 or 402 big block engine build. It's designed for those looking to put together a serious street and strip combination where reliable power is key. The assembly includes everything you need to get your short block started, ensuring compatibility between major components.

The I-beam connecting rods measure 6.135 inches long and are secured with 7/16-inch ARP 8740 bolts, offering solid strength for performance applications. Paired with these rods are forged 4032 Icon pistons featuring a 17cc open chamber dome design, which are sized for a 4.165-inch bore. These pistons come with plasma-moly file-fit rings, allowing for precise gap setting to optimize performance and sealing. The assembly also includes King SI rod and main bearings, known for their durability and performance under load, completing a well-matched package for your engine project.

When assembling this rotating unit, pay close attention to the file-fit nature of the piston rings, as proper gapping is crucial for engine health and performance. This assembly is a significant step towards building a powerful and reliable engine, but remember it is not CARB approved and cannot be shipped to California. Ensure all components are clean and properly lubricated during installation according to manufacturer guidelines.
