What is the compression ratio achieved with these pistons?

These Mahle pistons are designed to achieve a 10.4:1 compression ratio when used with a 4.250-inch stroke and a 6.700-inch rod. The -20cc dish volume is a key factor in reaching this ratio.

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

The pistons are constructed from 4032 aluminum. This material is chosen for its strength and thermal properties, making it well-suited for high-performance engine applications that experience significant heat and pressure.

Are these pistons legal for use in California?

No, these pistons are not CARB approved and cannot be shipped to California. It is important to check local regulations regarding emissions compliance for engine components.

Product Details

This Mahle MS Piston Set is built for Ford FE engines displacing 464 cubic inches. You get a complete set of eight forged pistons, each designed with a 4.170-inch bore, a 4.250-inch stroke compatibility, and a 6.700-inch rod length. The pistons feature a 0.990-inch pin diameter and a -20cc dish volume, contributing to a 10.4:1 compression ratio with a 4.250-inch stroke and 6.700-inch rod. Each piston weighs approximately 523 grams.

These pistons are constructed from 4032 aluminum, a material known for its strength and ability to handle high temperatures and pressures, making it a solid choice for performance builds. The -20cc dish volume is a key specification for achieving the target 10.4:1 compression ratio, which is a popular choice for many naturally aspirated and forced induction applications seeking a balance between power and pump gas compatibility. Mahle is a well-known name in engine components, and this set reflects their focus on providing well-built parts for serious engine work.

When rebuilding or upgrading your Ford FE engine, choosing the right pistons is critical for performance and reliability. This set from Mahle offers a specific combination of bore size, dish volume, and compression ratio that can be the foundation for a powerful and durable engine. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and assembly procedures.
