Eagle Chevy 400 3.750in Crank 5.700in I-Beam Rods -18cc 4.125in Pistons Rotating Assembly

Eagle has a long history of making well-built engine components, and this rotating assembly for the Chevy 400 is a prime example of their commitment to performance. If you're building a serious street or strip engine, this package gives you the core pieces you need to get started. It includes a 3.750-inch stroke crankshaft, 5.700-inch I-beam connecting rods, and a set of -18cc dish pistons designed for a 4.125-inch bore. This combination is designed to work together to form the heart of your engine build.

The I-beam connecting rods are known for their strength and reliability, making them a popular choice for many performance applications. The pistons are forged, which means they are incredibly strong and can handle the higher cylinder pressures found in performance engines. The -18cc dish volume on these pistons is a key specification that helps determine your final compression ratio when paired with your cylinder heads and block. This assembly is a solid foundation for anyone looking to upgrade their Chevy 400 engine.

When assembling an engine, it's crucial to have all your rotating components balanced. While this assembly provides the main parts, you'll want to ensure it's properly balanced by a professional machine shop before installation. This often involves balancing the assembly with your chosen flywheel or flexplate and harmonic balancer. Also, remember that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and balancing procedures.
