Mahle MS Piston Set Ford 487ci 4.27in Bore 4.250in Stroke 6.7in Rod 0.990 Pin -20cc 10.9 CR Set of 8

If you're rebuilding a Ford FE engine for serious performance, Mahle's MS Piston Set is a solid choice. This set is built for the 487 cubic inch displacement, featuring a 4.270 inch bore and a 4.250 inch stroke, designed to work with a 6.700 inch connecting rod and a 0.990 inch pin. These pistons are forged from 4032 aluminum, a material known for its strength and resistance to expansion, which is crucial for high-performance applications where temperatures can get quite high. The -20cc dish volume contributes to a 10.9:1 compression ratio when paired with the right cylinder heads and gasket combination, offering a noticeable bump in power without being excessively high for pump gas in many setups.

Mahle has a long-standing reputation for well-built engine components, and this piston set is no exception. The 4032 aluminum construction means they can handle the stresses of increased cylinder pressures and temperatures that come with a performance build. Each piston weighs in at approximately 527 grams, which is a good balance for strength and rotational mass. This set includes all eight pistons needed for a V8 engine, along with the necessary pins, making it a comprehensive solution for your engine's bottom end.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Also, be aware of the Prop 65 warning associated with this product. When planning your build, ensure your chosen cylinder heads and camshaft complement this compression ratio for optimal performance and reliability.
