Eagle Ford 351W 4.000in Crank 6.200in H-Beam -15.8cc 4.000in Pistons Rotating Assembly

This is a complete rotating assembly from Eagle, built for Ford 351 Windsor engines. It includes a 4.000-inch stroke crankshaft, 6.200-inch H-beam connecting rods, and pistons with a -15.8cc dish volume. This assembly is designed to be a core component for rebuilding or upgrading your 351W's bottom end, providing a solid foundation for increased displacement and performance.

The crankshaft is forged from high-strength steel, offering durability for demanding applications. The H-beam connecting rods are also forged, known for their strength and ability to handle higher horsepower and RPMs compared to I-beam designs. The pistons feature a -15.8cc dish, which will affect your final compression ratio depending on your cylinder head volume and deck height. This assembly is a popular choice for builders looking to increase displacement from the stock 351 cubic inches to approximately 393 cubic inches, assuming a stock 4.000-inch bore. It’s important to note that this assembly is not CARB approved and cannot be shipped to California.

When installing this rotating assembly, proper balancing by a professional machine shop is crucial to ensure smooth operation and longevity of your engine. You'll also need to consider your cylinder head choice and gasket thickness to achieve your desired compression ratio. This kit is a significant step towards building a powerful and reliable engine, but it requires careful attention to detail during the build process.
