What is the compression height of these pistons?

The compression height for this piston set is 4.125 inches. This measurement is taken from the center of the wrist pin bore to the top of the piston dome.

What is the significance of the -9cc dish volume?

The -9cc dish volume is a design feature that helps to achieve a specific compression ratio when paired with your cylinder heads. For this set, it results in a calculated 11.9:1 compression ratio.

Are these pistons suitable for use with a turbocharger or supercharger?

While these pistons are forged from strong 2618 aluminum, their 11.9:1 compression ratio is typically suited for naturally aspirated applications. For forced induction, a lower compression ratio is generally recommended. Always consult with an engine builder for forced induction setups.

Product Details

Mahle's MS Piston Set is built for serious Small Block Chevrolet builds aiming for a 359 cubic inch displacement. These pistons start with a 4.040-inch bore and are designed to work with a 3.500-inch stroke crankshaft and a 6.000-inch connecting rod, creating a compact 4.125-inch compression height. The -9cc dish volume is key here, working in conjunction with the cylinder head volume to achieve a calculated 11.9:1 compression ratio, which is ideal for many naturally aspirated performance applications where pump gas is still a consideration.

Crafted from 2618 aluminum alloy, these pistons are well-known for their strength and durability under high stress, making them a solid choice for performance engines. Each piston weighs in at 423 grams, contributing to a balanced rotating assembly. The 0.927-inch pin diameter is standard for many performance connecting rods. This set includes eight pistons, all engineered to Mahle's exacting standards for consistent performance and reliability in demanding engine builds.

When rebuilding your engine with these pistons, ensure you have the correct cylinder heads and camshaft to complement the compression ratio and intended use. Remember that this piston set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
