If you're building a high-performance Chevrolet Small Block engine, this Mahle MS Piston Set is a solid choice for your 427ci (or 428cid) application. These pistons are designed for a 4.125 inch bore and a 4.000 inch stroke, working with a 6.0 inch connecting rod and a .927 inch pin. Mahle is a well-known name in engine components, and this set is built to handle the demands of a performance build.

These pistons feature a -5cc dish volume, which helps achieve a 12.2:1 compression ratio with the specified stroke and rod length. The 4032 aluminum alloy construction offers good strength and durability for performance use, while keeping the weight down to around 404 grams per piston. This set includes eight pistons, ready to be installed in your engine build. Remember that these pistons are not CARB approved and cannot be shipped to California.
