Product Details

Mahle is well-known for making solid engine components, and this MS Piston Set is a great example of their work for performance builds. This set is specifically designed for Ford FE 447 cubic inch engines, giving you a strong foundation for a serious rebuild. If you're putting together a high-performance engine, getting the pistons right is one of the most critical steps, and Mahle has a reputation for delivering reliable parts.

This particular set features a 4.090-inch bore and a 4.250-inch stroke, working together to create a 447 cubic inch displacement. The pistons are made from 4032 aluminum, which is a strong material often used in performance applications because it handles heat well and has good expansion properties. They come with a -18cc dish volume, which helps achieve a 10.1 compression ratio when paired with the specified stroke and rod length. The included wrist pin is .990 inches, a common size for performance applications. Each piston weighs in at 496 grams, which is a good balance for strength and rotational mass in a performance engine.

When you're building an engine of this caliber, it's important to ensure all the components work together. This piston set is designed to be used with a 6.7-inch connecting rod and a 4.250-inch stroke crankshaft. Remember that this set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures to get the most out of these Mahle pistons.
