Eagle Ford 351W 4.000in Crank 6.200in I-Beam Rods -15.8cc 4.040in Pistons Rotating Assembly

This is the Eagle Ford 351W 4.000in crank, 6.200in I-beam rods, and 4.040in pistons rotating assembly. It's a well-built package designed to form the core of a performance or rebuilt Ford 351 Windsor engine. A rotating assembly is essentially the heart of your engine's bottom end, containing the crankshaft, connecting rods, and pistons. Getting these components balanced and matched correctly is crucial for engine longevity and smooth operation, especially when you're aiming for more power or a reliable rebuild.

Eagle has put together a solid option here with a 4.000-inch stroke crankshaft, which is a common upgrade for increasing displacement in a 351W. The 6.200-inch I-beam connecting rods are a popular choice for many builds, offering a good balance of strength and weight. They're paired with 4.040-inch pistons that feature a -15.8cc dish. This dish volume is important because it affects your engine's compression ratio when combined with your cylinder heads and head gasket thickness. Eagle is known for producing reliable engine components, and this assembly is no exception, giving you a strong foundation for your project.

When you're building an engine, especially one that will see higher performance demands, starting with a balanced and matched rotating assembly like this one saves a lot of guesswork and potential issues down the line. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always consult your engine builder or a trusted mechanic to ensure this assembly is the right fit for your specific build goals and that all necessary supporting components, like bearings and rings, are accounted for during your build.
