Eagle Ford 351W Block Pro Street Rotating Assembly - 6.25in I-Beam +.040in Bore (Unbalanced)

If you're building a Ford 351 Windsor for naturally-aspirated racing, this Eagle Pro Street Rotating Assembly is a solid foundation. It's designed to handle the demands of the track and give you a strong starting point for your engine build.

This assembly features a 4.000-inch forged 4340 steel crankshaft, built for durability. The connecting rods are 6.250-inch I-beam style, also made from 4340 steel, and they come equipped with 7/16-inch ARP 8740 bolts for a strong, reliable connection. For the pistons, you get forged 4032 Mahle pistons with a -20cc inverted dome, designed for a 4.040-inch bore. They're paired with plasma-moly file-fit rings, which allow for precise gap setting to match your specific engine build. To top it off, the kit includes King XP rod and main bearings, known for their robust performance.

This is an unbalanced rotating assembly, meaning you'll need to have it professionally balanced to match your specific application and flywheel/flexplate combination. Please note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and balancing procedures.
