Eagle Ford 289/302 347 Rotating Assembly Kit - +.030 Bore

This Eagle rotating assembly kit gives you the core components to rebuild or upgrade your Ford 289, 302, or 347 cubic inch engine. Inside this kit, you'll find a 3.400-inch stroke forged 4340 crankshaft, a set of 5.400-inch H-beam connecting rods equipped with 7/16-inch ARP 8740 bolts, and forged 2618 Mahle pistons designed for a 4.030-inch bore with a 7cc dome. It also includes plasma-moly file-fit rings and King XP rod and main bearings to complete the assembly.

This is a well-built competition-grade assembly, suitable for demanding applications like racing, including those using nitrous or forced induction. The forged 4340 crankshaft offers a strong foundation for high-horsepower builds, while the H-beam rods with ARP bolts are known for their durability under stress. The Mahle pistons are forged for strength and feature a dome design that works with specific cylinder head combustion chambers to achieve a target 7cc volume. The included file-fit rings allow for precise gap setting, which is crucial for optimal performance and sealing in a performance engine. King XP bearings are chosen for their robust construction and ability to handle the increased loads of a performance engine.

This kit is specifically sized for a 4.030-inch bore, which is +.030 inches over the stock 3.75-inch bore for a 302 engine, resulting in a 347 cubic inch displacement. Please note that this assembly is not CARB approved and cannot be shipped to California. It's essential to ensure all components are properly balanced and installed according to manufacturer specifications for optimal performance and longevity.
