What is the compression ratio achieved with this piston set?

This Mahle MS piston set, with its -7.4cc dish volume and specific bore, stroke, and rod length, is designed to achieve a calculated compression ratio of 11.8:1. This is a common target for performance-oriented Ford FE engine builds.

What materials are these pistons made from and why is that important?

These pistons are made from 4032 aluminum. This alloy is chosen for its good strength and controlled thermal expansion, which helps prevent piston seizure and maintain proper clearances as the engine heats up during operation, making it suitable for performance applications.

Are these pistons suitable for use in California?

No, this Mahle MS Piston Set is not CARB approved and cannot be shipped to California due to emissions regulations. It is intended for use in areas where such regulations do not apply or for dedicated racing applications.
