What is the compression ratio with these pistons?

These pistons feature a -16cc dish volume, which results in a 9.4:1 compression ratio when used with the specified 363 cubic inch Ford Small Block engine configuration and compatible components.

What material are these pistons made from and why is it important?

The pistons are forged from 4032 aluminum alloy. This material is chosen for its strength and its ability to manage thermal expansion, which is crucial for high-performance engines that experience significant heat and stress.

Are these pistons legal for use in California?

No, these pistons are not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

These Mahle MS Series pistons are forged from 4032 aluminum, a material chosen for its strength and ability to handle the thermal expansion that comes with high-performance engine builds. This specific set is designed for a 363 cubic inch Ford Small Block engine, featuring a 4.125-inch bore and a 3.4-inch stroke, which works with a 5.4-inch connecting rod and a .927-inch wrist pin. The -16cc dish volume combined with the piston crown design results in a 9.4:1 compression ratio when used with the specified engine configuration.

The 4032 aluminum alloy offers a good balance between durability and weight, with a typical piston weight around 395 grams for this application. This material choice helps manage heat and expansion, reducing the risk of piston seizure in demanding conditions. Mahle's MS Series pistons are a popular choice for builders looking for a well-built, reliable component for their performance engine projects. They are designed to fit right and perform consistently under stress.

This set includes eight pistons, ready for your next engine build. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures to ensure optimal performance and longevity of your engine.
