Eagle Ford 351W 4.000in Crank 6.200in I-Beam Rods -15.8cc Flat Top 4.030in Pistons Rotating Assembly

If you're building a Ford 351 Windsor engine and need a strong rotating assembly to handle more power, this Eagle kit is a solid choice. It includes a 4.000-inch stroke crankshaft, 6.200-inch I-beam connecting rods, and 4.030-inch flat-top pistons with a -15.8cc dish, all designed to work together as a balanced unit for your engine.

Eagle is known for making well-built internal engine components, and this assembly is no exception. The crankshaft is forged from high-strength steel, giving it the durability needed for performance applications. The I-beam connecting rods are also forged, offering a strong and reliable link between the pistons and the crankshaft. The pistons are designed for a flat-top configuration with a slight dish, which is common for many performance builds and helps achieve a desired compression ratio when paired with the right cylinder heads. This assembly is balanced, meaning the components have been precisely weighted to reduce vibration and ensure smooth engine operation.

This rotating assembly is a critical part of your engine's foundation. It's designed to be a direct replacement for the stock rotating assembly in a Ford 351W block, but it's built to handle more stress than factory parts. You'll want to ensure you have the correct machine work done on your block, including honing and deck squaring, to properly accommodate this assembly. Remember, this kit is not CARB approved and cannot be shipped to California.
