Eagle Ford 351W Balanced Rotating Assembly with .040in Over Bore -5.0cc Dome

When you're rebuilding the heart of your Ford 351W, this balanced rotating assembly from Eagle gives you a solid foundation. What you get in this kit is a complete package designed for street use with pump gas and naturally aspirated setups. It includes a 4.000-inch cast crankshaft, 6.250-inch I-beam connecting rods fitted with 3/8-inch ARP 8740 bolts, and forged 4032 Mahle pistons. These pistons are a 4.040-inch bore size with a -5.0cc dome dish, and the assembly comes with plasma-moly file-fit rings and King rod and main bearings.

This assembly is balanced from the factory, which is a critical step for smooth engine operation and longevity, especially when you're pushing your engine. The Mahle pistons are forged, meaning they're built to handle the stresses of combustion better than cast pistons, and the 4.040-inch bore size is .040 inches over the standard 4.000-inch bore, often used to clean up cylinder walls or achieve a specific displacement. The ARP bolts used on the connecting rods are well-known for their strength and reliability, ensuring the rods stay securely attached under load. The included King bearings are a popular choice for their performance and durability in street applications.

This Eagle rotating assembly is intended for street vehicles running on pump gas and without forced induction or nitrous. 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 installation instructions for proper assembly and break-in procedures to ensure the best performance and lifespan for your new engine components.
