What is the compression ratio achieved with these pistons?

These pistons have a -6.5cc dish volume. When used with compatible cylinder heads and gaskets, they are designed to achieve a 10.3:1 compression ratio, which is a common target for performance builds.

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

The pistons are forged from 4032 aluminum. This material is chosen for performance applications because it offers greater strength and thermal stability compared to cast aluminum, allowing it to withstand higher cylinder pressures and temperatures.

Are these pistons compatible with all Ford Small Block engines?

This set is specifically designed for Ford Small Block engines with a 358 cubic inch displacement and a 4.030 inch bore. It's important to confirm your engine's exact specifications to ensure proper fitment.

Product Details

If you're rebuilding the heart of your Ford Small Block engine for serious performance, a solid set of pistons is where it all starts. This Mahle MS Piston Set is built for the 358 cubic inch displacement, featuring a 4.030-inch bore and a 3.5-inch stroke. These pistons are crafted from 4032 aluminum, a material known for its strength and ability to handle higher temperatures and pressures compared to cast aluminum, making them a well-built choice for performance applications.

With a -6.5cc dish volume, these pistons help achieve a 10.3:1 compression ratio when paired with the right cylinder heads and gasket combination. This compression level is a popular target for naturally aspirated performance builds, offering a noticeable increase in power and throttle response without being so extreme that it requires exotic fuel. The pistons measure 5.956 inches in rod length compatibility and use a standard 0.912-inch wrist pin, common in many performance engine builds. Each piston weighs in at 489 grams, contributing to a balanced rotating assembly.

This set includes all eight pistons needed for a V8 engine. Please note that these pistons are not CARB approved and cannot be shipped to California. They also carry a Prop 65 warning. Ensure you have the correct supporting components, such as appropriate connecting rods, rings, and cylinder heads, to complete your engine assembly.
