This Mahle MS Piston Set is built for Big Block Chevy 565 cubic inch engines with a standard deck height. You get a complete set of eight pistons, designed to work with a 4.600-inch bore and a 4.250-inch stroke, utilizing a 6.385-inch connecting rod and a 0.990-inch pin. These pistons feature a -3.4cc dish, contributing to a 9.8:1 compression ratio when paired with the right cylinder heads and gasket combination.

Mahle has constructed these pistons from 4032 aluminum, a material known for its strength and thermal expansion properties, making it a solid choice for high-performance applications. The flat-top design with a valve relief (1.270RCH) helps ensure proper valve clearance in many performance camshaft profiles. Each piston weighs in at approximately 562 grams, which is a well-balanced weight for consistent engine operation at higher RPMs. This set is intended for performance builds where precise engine component matching is key to achieving desired power and reliability.

It's important to note that this piston set is not CARB approved and cannot be shipped to California. Always refer to your engine builder's recommendations and manufacturer installation instructions for proper assembly and tuning to achieve the best results from this performance component.
