Eagle Ford 351C 4.000in Crank 6.000in H-Beam -18cc 4.060in Pistons Rotating Assembly

This Eagle rotating assembly starts with a 4.000-inch stroke crankshaft, forged from 4340 steel for strength. It's paired with 6.000-inch long H-beam connecting rods, also forged from 4340 steel, which are known for their robust design and ability to handle significant stress. The assembly includes -18cc dish pistons designed for a 4.060-inch bore, allowing for a specific compression ratio tailored for performance builds. This combination is built to handle the demands of a performance-oriented Ford 351 Cleveland engine.

The choice of 4340 steel for both the crankshaft and connecting rods means you're getting components that offer a strong balance of durability and weight. H-beam rods are a popular choice for performance applications because their I-beam cross-section is reinforced, making them very rigid and resistant to bending or breaking under high cylinder pressures and RPMs. The -18cc dish in the pistons helps to control compression ratio, which is crucial when matching the engine to specific camshafts, cylinder heads, and intended use, whether that's street performance or track duty. This assembly is a well-built foundation for rebuilding or upgrading your 351 Cleveland.

When building a performance engine, the rotating assembly is the heart of the operation. This Eagle kit provides a matched set of critical components, simplifying the process of sourcing parts that work together. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Ensure you have the correct machine work done on your block to accommodate the 4.060-inch bore and that all clearances are checked according to manufacturer specifications before final assembly.
