Mahle MS Piston Set SBC 358ci 4.040in Bore 3.480/3.5stk 6.125in Rod .927 Pin -5cc 10.4 CR Set of 8

These Mahle MS forged pistons are built with 4032 aluminum, a material known for its strength and ability to handle the heat and stress of high-performance engines. They feature a -5cc dish volume, which, when paired with the 3.480/3.500-inch stroke and 6.125-inch rod length, helps achieve a 10.4:1 compression ratio. This specific compression ratio is a popular choice for naturally aspirated or forced induction street/strip applications, offering a good balance of power and drivability.

Each piston weighs in at 423 grams, contributing to a well-balanced rotating assembly, which is crucial for engine longevity and smooth operation at higher RPMs. The 0.927-inch pin diameter is standard for many performance small block Chevy builds. Mahle is a well-known name in engine components, and this set is designed to be a solid option for anyone rebuilding or upgrading their Chevrolet Small Block engine, specifically for the 357 cubic inch displacement.

This set includes eight pistons, enough for a complete 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 specific assembly and clearance recommendations to ensure optimal performance and reliability for your build.
