Mahle MS Piston Set SBC 388ci 4.060in Bore 3.75in Stroke 5.7in Rod 0.927 Pin -16cc 10.0 CR Set of 8

If you're building a high-performance Small Block Chevrolet engine, a solid set of pistons is where it all starts. This Mahle MS piston set is built for a 388 cubic inch displacement, featuring a 4.060-inch bore and a 3.750-inch stroke, designed to work with a 5.700-inch connecting rod and a 0.927-inch wrist pin. These pistons are forged from 4032 aluminum, a material known for its strength and resistance to expansion, which is crucial for maintaining proper clearances under high heat and stress. This helps ensure a longer engine life and consistent performance.

The -16cc dish volume on these pistons, combined with the other specified dimensions, results in a 10.0:1 compression ratio when used with compatible components. This compression level is a popular choice for street/strip applications, offering a good balance between power and drivability. Each piston weighs in at approximately 470 grams, contributing to a well-balanced rotating assembly. This set includes all eight pistons needed for a complete engine build. Please note that these pistons are not CARB approved and cannot be shipped to California.
