If you're building a high-performance Ford Small Block engine and aiming for a 408 cubic inch displacement, this Mahle MS Piston Set is a solid choice. These pistons are specifically designed for a 4.030-inch bore and are engineered to work with a 4.000-inch stroke crankshaft and a 6.250-inch connecting rod, achieving a compression ratio of 11.6:1. This setup is ideal for enthusiasts looking to extract significant power from their Ford V8.

Mahle is well-known for its engine components, and this piston set is crafted from 2618 aluminum, a strong material commonly used in performance applications for its durability and heat resistance. Each piston weighs in at 437 grams, contributing to a balanced rotating assembly. The pistons feature a -6.5cc dish volume, which is crucial for achieving the target compression ratio with specific cylinder head volumes. The 0.927-inch pin diameter is standard for many performance connecting rods, ensuring broad compatibility.

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. It's always recommended to consult with your engine builder or refer to Mahle's technical documentation for precise assembly details and compatibility with other engine components like cylinder heads and gaskets to ensure optimal performance and longevity.
