Product Details

If you're building a high-performance Small Block Chevrolet engine, this Mahle MS Piston Set is a solid choice for your 422 cubic inch application. Mahle is a well-known name in engine components, and these pistons are designed to handle the demands of a performance build. They feature a 4.165-inch bore and are engineered to work with a 3.875-inch stroke and a 6.0-inch connecting rod, creating a 422 cubic inch displacement. The included .927-inch pins are standard for many performance applications.

These pistons are forged from 4032 aluminum, a material chosen for its strength and durability under high temperatures and pressures. This specific set is designed to achieve a 10.1 compression ratio with a -22cc dish volume, which is a popular target for many naturally aspirated or forced induction builds aiming for a good balance of power and pump gas compatibility. Each piston weighs in at 451 grams, contributing to a well-balanced rotating assembly. This set includes eight pistons, enough for a complete V8 engine.

It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to your engine builder's specifications and the manufacturer's installation instructions for proper assembly and tuning. This set is a key component for anyone looking to build a robust and powerful Small Block Chevrolet engine.
