Product Details
This Mahle MS Piston Set is built for Ford Small Block 394 cubic inch engines. If you're rebuilding the heart of your performance Ford, these pistons are a solid choice for handling increased power and stress. They're designed to work with a 4.040-inch bore and a 3.85-inch stroke, featuring a 5.956-inch rod length and a .912-inch pin diameter. The -26cc dish volume results in a 9.2:1 compression ratio, which is a popular target for many performance builds looking for a good balance of power and pump gas drivability.
Mahle uses a 4032 aluminum alloy for these pistons, a well-known material in performance engine building. This alloy offers a good balance of strength and thermal expansion properties, making it suitable for demanding applications where reliability is key. Each piston weighs in at 473 grams, which is a reasonable weight for a forged piston of this size. The set includes eight pistons, all the necessary components for a complete engine rebuild. Remember that these pistons are not CARB approved and cannot be shipped to California.
