Eagle Ford 351W 4.000in Crank 6.250in I-Beam Rods -26cc Inv Dome 4.125in Pistons Rotating Assembly

If you're building a Ford 351W for serious naturally-aspirated racing, a strong rotating assembly is the heart of the operation. This Eagle Pro Street rotating assembly is designed to handle the demands of high-performance builds where every component needs to be solid. It's a complete package that gives you the core pieces to get your engine project moving forward with confidence.

At the center of this assembly is a 4.000-inch stroke crankshaft forged from 4340 steel, known for its strength and durability under stress. Paired with this are 6.250-inch I-beam connecting rods, also made from robust 4340 steel, and secured with 7/16-inch ARP 8740 bolts. These bolts are a popular choice for their reliability in high-stress applications. The pistons are forged 4032 aluminum from Mahle, featuring a -26cc inverted dome design and a 4.125-inch bore size, which are crucial for achieving specific compression ratios in performance builds. This assembly also includes plasma-moly file-fit piston rings, allowing for precise ring gap adjustment, and King XP series rod and main bearings, which offer improved performance and durability for racing conditions.

This rotating assembly is a well-built foundation for a powerful Ford 351W engine. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. For optimal results and longevity, always refer to the manufacturer's detailed installation instructions and recommended clearances.
