Eagle Ford 351W 4.170in Crank 6.300in H-Beam -18cc 4.040in Pistons Rotating Assembly

This Eagle rotating assembly starts with a 4.170-inch stroke crankshaft, forged from 4340 steel for strength and durability. This is a substantial piece designed to handle the demands of a performance Ford 351 Windsor engine build. The crankshaft's robust construction is key to reliably transferring power from the pistons to the rest of your drivetrain, especially when you're pushing the limits.

Paired with the crankshaft are 6.300-inch long H-beam connecting rods, also forged from 4340 steel. The H-beam design offers a strong yet relatively lightweight profile, making them a popular choice for performance applications. These rods connect the pistons to the crankshaft, and their length is a critical factor in engine geometry and piston speed. The assembly includes 4.040-inch bore pistons with a -18cc dish volume. This dish volume is important for determining your final compression ratio when combined with your cylinder heads and gasket thickness. The pistons are designed to fit the 4.040-inch bore size, ensuring a proper seal and efficient combustion.

This complete rotating assembly is a significant step towards building a powerful and reliable Ford 351W engine. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed specifications and installation instructions for proper assembly and tuning to achieve the best results for your specific build.
