Ford Racing High Strength Forged Steel 3.40inch Stroker Crankshaft

When you're building a high-performance 347 cubic inch engine from a 302 block, you need a crankshaft that can handle the extra stress. This Ford Racing High Strength Forged Steel 3.40-inch Stroker Crankshaft is built for that purpose. It's designed to fit both 302 production blocks and Ford Performance cylinder blocks, giving you a solid foundation for your project. You'll be using stock 2.1232-inch rod journal diameters, which works with specific aftermarket components to achieve the 347 displacement.

This crankshaft is forged from high-strength steel for durability and features lightening holes to reduce rotational mass. The journals are nitrided and polished, a process that hardens the surface and creates a smooth finish, which is crucial for reducing friction and wear on bearings. The leading edge of the counterweights is rounded for improved oil flow, and the trailing edge is tapered. To make this crankshaft work, you'll need custom pistons, specific aftermarket rods like the M-6200-D50 'Sportsman' rods (5.40 inches long), and 1.090-inch CD pistons, along with professional balancing. This is a serious component for a serious engine build, suitable for a wide range of classic Ford vehicles including the F-150, Gran Torino, and Econoline vans.
