Mahle MS Piston Set SBF 462ci 4.160in Bore 4.250in Stroke 6.7in Rod .990 Pin -20cc 10.4 CR Set of 8

If you're building a high-performance Ford FE engine for serious street or track use, Mahle's MS Piston Set for 462 cubic inch applications is a solid choice. These pistons are designed to handle the demands of a performance build, offering a good balance of strength and weight for your engine.

This set features a 4.160-inch bore and is designed to work with a 4.250-inch stroke and a 6.700-inch connecting rod, creating a 462 cubic inch displacement. The pistons are forged from 4032 aluminum, a material known for its durability and resistance to expansion, which is crucial in high-heat performance engines. They come with a -20cc dish volume, resulting in a 10.4:1 compression ratio when paired with the right cylinder heads and gasket combination. This compression ratio is well-suited for naturally aspirated performance builds, offering a noticeable improvement in power output without being excessively sensitive to fuel octane. The included wrist pins are 0.990 inches in diameter, a common size for performance applications.

Each piston weighs in at approximately 519 grams, contributing to a well-balanced rotating assembly. Mahle is a well-known name in engine components, and this piston set reflects their commitment to producing reliable parts for performance engine builders. Please note that this piston set is not CARB approved and cannot be shipped to California. Always consult your engine builder or a professional mechanic for specific installation recommendations and compatibility with other engine components.
