Mahle is a well-known name in engine components, recognized for their focus on precision and performance. This Mahle MS Piston Set is built for the demanding needs of a Big Block Chevy 565 cubic inch engine. If you're building or rebuilding a high-performance Big Block Chevy, these pistons are designed to handle the power and stress of a larger displacement engine.

This set includes eight pistons, each featuring a 4.600-inch bore and a 4.250-inch stroke, paired with a 6.385-inch connecting rod and a 0.990-inch pin. The pistons have a 38cc dome volume, which contributes to a 13.7:1 compression ratio when used with a standard deck height (9.800 inches) and the specified stroke and rod length. Each piston weighs in at 623 grams, indicating a solid construction suitable for high-output applications. The material used, 2618 aluminum alloy, is known for its strength and ability to withstand high temperatures and pressures, making it a popular choice for performance engine builds.

When installing these pistons, ensure you follow the manufacturer's recommended clearances and procedures for the 2618 aluminum alloy to achieve optimal performance and longevity.
