Eagle Ford 351W 408 Stroker Rotating Assembly Kit

This is the Eagle Ford 351W 408 Stroker Rotating Assembly Kit, designed for serious performance builds. If you're looking to significantly increase the displacement and power potential of your Ford 351 Windsor engine, this balanced assembly is a solid foundation. It's built to handle the demands of racing, including the extra stress from nitrous and forced induction setups.

At the heart of this kit is a forged 4340 steel crankshaft with a 4.000-inch stroke, which is what creates the 408 cubic inch displacement when paired with the included 4.030-inch bore pistons. The connecting rods are 6.250-inch long H-beam units, made from strong 4340 steel and secured with 7/16-inch ARP 8740 bolts for reliable performance under high load. The pistons are forged 4032 aluminum flat-tops with a -6.6cc dish, designed to work with the crank and rod combination to achieve a specific compression ratio. They come with plasma-moly file-fit rings, which allow for precise gapping to match your engine's needs. To finish it off, the kit includes King XP rod and main bearings, known for their durability and performance.

This assembly comes balanced from Eagle, saving you a significant step and cost in your engine build. It's important to note that this kit is not CARB approved and cannot be shipped to California. You'll want to ensure you have all the necessary machine work done, such as boring and honing the cylinders to 4.030 inches, and checking clearances before assembly. This is a comprehensive rotating assembly that sets the stage for a powerful, custom engine.
