Mahle MS Piston Set SBC 406ci 4.155in Bore 3.75in Stroke 6.0in Rod .927 Pin 11cc 14.4 CR Set of 8

This Mahle MS Piston Set is designed for Chevrolet Small Block engines, specifically for builds targeting around 406 cubic inches. You get a complete set of eight forged pistons, ready to be installed in your performance engine. These pistons are built to handle the demands of a high-compression, high-performance application, making them a solid choice for engine rebuilders looking for reliable components.

Mahle uses a strong 2618 aluminum alloy for these pistons, which is well-known for its durability and ability to withstand high temperatures and pressures common in performance engines. The specific dish volume is 11cc, and combined with the bore size of 4.155 inches and stroke of 3.75 inches, these pistons are designed to achieve a 14.4:1 compression ratio. This high compression ratio is ideal for naturally aspirated engines seeking maximum power output. The pistons also feature a 6.0-inch rod length compatibility and a standard .927-inch wrist pin diameter, common in many performance Small Block Chevy builds. Each piston weighs approximately 507 grams, contributing to a balanced rotating assembly.

When building a performance engine, especially one with a high compression ratio like this set enables, it's crucial to ensure your camshaft, cylinder heads, and tuning are all matched to take full advantage of these pistons. Remember that this piston set is not CARB approved and cannot be shipped to California. Always consult your engine builder or a qualified professional for specific installation and tuning recommendations to achieve optimal performance and longevity from your engine build.
