Mahle MS Piston Set SBF 447ci 4.090in Bore 4.250in Stroke 6.7in Rod .990 Pin -7cc 11.3 CR Set of 8

If you're building a high-performance Ford FE engine, a solid set of pistons is crucial for handling the extra power and stress. This Mahle MS Piston Set is designed for 447 cubic inch applications, featuring a 4.090-inch bore and a 4.250-inch stroke, which are key dimensions for achieving that displacement. These pistons are crafted from 4032 aluminum, a material known for its strength and durability, making it a popular choice for performance builds where reliability is paramount.

With a -7.4cc dish volume, these pistons contribute to an 11.4:1 compression ratio when paired with the right cylinder heads and gasket combination, offering a noticeable boost in power and throttle response for your FE engine. The 6.700-inch connecting rod length and 0.990-inch pin diameter are specific measurements that ensure proper fitment and geometry within the engine assembly. Each piston weighs in at 477 grams, which is a well-balanced weight for performance applications, helping to reduce overall engine vibration and stress on the rotating assembly.

This set includes eight pistons, ready to be installed in your Ford FE 447 cubic inch engine. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For a successful build, ensure you have the correct connecting rods, crankshaft, and cylinder heads that match these specifications. Always refer to Mahle's installation guidelines for proper fitment and assembly procedures.
