Eagle Chevy 400 3.750in Crank 5.700in I-Beam Rods -18cc 4.165in Pistons Rotating Assembly

If you're building a high-performance Chevy 400 small block engine, a strong rotating assembly is the heart of your build. This Eagle 13016040 rotating assembly is designed to handle the demands of a performance engine, providing a solid foundation for your project. It includes a 3.750-inch stroke crankshaft, 5.700-inch I-beam connecting rods, and -18cc dish pistons, all balanced and ready for installation.

The crankshaft in this assembly is forged from durable steel, built to withstand the increased cylinder pressures and stresses of a performance application. Paired with the I-beam connecting rods, which offer a good balance of strength and weight for their class, this setup is well-suited for street performance and moderate racing use. The -18cc dish pistons are designed to work with the 3.750-inch stroke and a typical 4.165-inch bore to achieve a specific compression ratio, making them a key component in tuning your engine's power output. This assembly comes balanced, which is a critical step to ensure smooth operation and longevity for your engine.

This rotating assembly is a significant step towards building a powerful and reliable engine. It's important to note that this assembly is not CARB approved and cannot be shipped to California. When installing, ensure all clearances are checked and proper lubrication is applied to all bearing surfaces. You will also need to source appropriate piston rings, bearings, and main bearings, as these are typically sold separately for custom engine builds.
