If you're building a Ford 351 Windsor for naturally-aspirated racing, this Eagle Pro Street rotating assembly is a solid foundation. It bundles together the key components you'll need to get your engine's bottom end put together, saving you time and ensuring compatibility between major parts. This assembly is designed to handle the demands of racing applications where forced induction isn't being used.

At the heart of this kit is a 4.170-inch forged 4340 crankshaft, known for its strength and durability under stress. Paired with it are 6.250-inch 4340 I-beam connecting rods, which are also well-built for racing. These rods come equipped with 7/16-inch ARP 8740 bolts, a name you can trust for secure and reliable connections. The pistons are forged 4032 Mahle flat tops, featuring a -6cc dish and a 4.030-inch bore size, ready for your custom build. You'll also find plasma-moly file-fit piston rings included, allowing for precise ring gap adjustment to match your engine's specific needs. To round out the assembly, King XP rod and main bearings are part of the package, offering robust lubrication and wear protection for critical rotating components.
