Eagle Ford 351W 408 Competition Rotating Assembly Kit

This Eagle Ford 351W 408 Competition Rotating Assembly Kit gives you the core components to build a strong, high-performance engine. Inside this kit, you'll find a 4.000-inch forged 4340 steel crankshaft, ready to handle serious power. Paired with it are 6.200-inch H-beam connecting rods, which are known for their strength and reliability under stress. These rods come equipped with 7/16-inch ARP 8740 bolts, a popular choice for their durability and consistent clamping force.

The kit also includes forged 4032 aluminum pistons from Mahle. These pistons feature a -28cc inverted dome design and are sized at 4.030 inches, intended for a 408 cubic inch displacement when combined with the crankshaft. You also get plasma-moly file-fit piston rings, which allow for precise gapping to match your engine's specific needs and intended use, especially important for racing applications. To round out the assembly, King XP rod and main bearings are included, offering solid lubrication and wear protection for critical rotating components.

This assembly is built for demanding use, including racing with nitrous or forced induction. Please note that this kit is not CARB approved and cannot be shipped to California. It's a well-built foundation for a powerful Ford 351W build.
