Eagle Ford 351W 4.170in Crank 6.250in H-Beam -16cc 4.030in Pistons Balanced Assembly

This is a balanced rotating assembly from Eagle, built for Ford 351W engines. It includes a forged 4340 steel crankshaft with a 4.170-inch stroke, 6.250-inch H-beam connecting rods secured with 7/16-inch ARP 8740 bolts, and 4.030-inch Mahle forged pistons with an inverted dome design and a -16cc volume. This assembly is designed for serious performance applications, including racing, and is balanced from the factory to save you time and ensure proper operation.

The forged 4340 steel crankshaft is a strong foundation for high-horsepower builds, offering excellent durability under stress. The H-beam connecting rods are also forged and come with ARP bolts, known for their reliability in demanding conditions. The Mahle pistons are made from 4032 aluminum, which offers a good balance of strength and thermal expansion properties for performance use. They feature an inverted dome design with a -16cc volume, which is typically used to achieve a specific compression ratio when paired with the right cylinder heads and gasket thickness. The assembly also includes plasma-moly file-fit piston rings, allowing for precise gap setting to match your engine's bore and intended use, and King XP series rod and main bearings for robust lubrication and wear resistance.

This balanced rotating assembly is a significant upgrade for anyone looking to build a high-performance Ford 351W engine. It’s important to note that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations. Always consult with your engine builder or refer to manufacturer specifications for proper installation, ring gap settings, and compatibility with other engine components to achieve your desired performance goals.
