This is the Eagle Ford 351W Street & Strip Rotating Assembly, built for naturally aspirated street applications running on pump gas. If you're rebuilding the heart of your Ford 351 Windsor, this assembly gives you the core components needed to get your engine back to life with improved performance for daily driving and spirited runs.

At its core is a 4.000-inch cast crankshaft, paired with 6.200-inch I-beam connecting rods. These rods are secured with 3/8-inch ARP 8740 bolts, a strong choice for street performance that ensures reliability. The assembly includes Hypereutectic KB pistons, specifically flat-top with a -6.5cc dish, sized for a 4.040-inch bore. These pistons come with plasma-moly file-fit rings, allowing for precise gap setting during installation to match your engine's specific needs. To complete the package, King SI rod and main bearings are included, offering solid lubrication and wear protection for the rotating assembly.

This rotating assembly is a well-built foundation for your 351W build. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and break-in procedures.
