This Mahle MS Piston Set includes eight forged pistons designed for a Chevrolet Small Block engine with a 385 cubic inch displacement. These pistons feature a 4.040-inch bore and a 3.750-inch stroke, with a 5.700-inch rod length and a 0.927-inch pin diameter. The dish volume is -5cc, which results in a compression ratio of approximately 11.2:1 with the specified components. Each piston weighs around 464 grams and is constructed from 4032 aluminum alloy.

Mahle's MS series pistons are built for performance applications where strength and reliability are key. The 4032 aluminum alloy offers a good balance of strength and thermal expansion properties, making it suitable for demanding engine builds. The forged construction provides a well-built component that can withstand higher cylinder pressures and temperatures compared to cast pistons. The specific dish volume and bore size are engineered to achieve a target compression ratio, which is crucial for optimizing engine power and efficiency in a 385 cubic inch Small Block Chevy.

When rebuilding or modifying your engine, selecting the right pistons is critical for overall performance and longevity. This set from Mahle is a solid option for builders looking for a specific bore size and compression ratio for their Small Block Chevy project. Please note that these pistons are not CARB approved and cannot be shipped to California. Always consult your engine builder or Mahle's technical documentation for specific installation guidelines and compatibility with other engine components.
