Mahle MS Piston Set SBC 408ci 4.165in Bore 3.75in Stroke 5.7in Rod 0.927 Pin -20cc 10.0 CR Set of 8

If you're building a high-performance Chevrolet Small Block engine, this Mahle MS Piston Set is a solid choice for your 408 cubic inch application. These pistons are specifically designed for a 4.165-inch bore and a 3.75-inch stroke, working with a 5.7-inch connecting rod and a 0.927-inch pin. Mahle is a well-known name in engine components, and this set is built to handle the demands of a performance build.

What sets these pistons apart is their construction and design for optimal performance. They feature a -20cc dish volume, which, when combined with your cylinder head volume and bore/stroke dimensions, helps achieve a 10.0:1 compression ratio. This compression ratio is a popular target for many naturally aspirated and forced induction street/strip builds, offering a good balance of power and pump gas compatibility. The pistons are forged from 4032 aluminum, a material known for its strength and resistance to thermal expansion, making them well-suited for the higher temperatures and pressures found in performance engines. Each piston weighs in at 519 grams, which is a reasonable weight for a forged piston of this size, contributing to good rotational balance.

This set includes eight pistons, enough for a complete V8 engine. It's important to note that these pistons are not CARB approved and cannot be shipped to California. When planning your build, ensure you have the correct supporting components, such as appropriate rings, bearings, and cylinder heads, to match the specifications of these Mahle pistons for a successful engine assembly.
