Mahle MS Piston Set SBC 358ci 4.03in Bore 3.500in Stroke 5.7in Rod .927in Pin -4cc 10.5 CR Set of 8

This Mahle MS Piston Set is built for Chevrolet Small Block engines displacing 357 cubic inches. You get a complete set of eight forged pistons, designed to work with a 4.030-inch bore and a 3.500-inch stroke, utilizing a 5.700-inch connecting rod and a .927-inch wrist pin. These pistons feature a -4.1cc dish volume, which contributes to a 10.5:1 compression ratio when paired with the correct cylinder heads and gasket combination.

Mahle uses 4032 aluminum alloy for these pistons, a material known for its strength and durability, making it a solid choice for performance builds. The forged construction offers improved resistance to detonation and higher cylinder pressures compared to cast pistons. Each piston weighs in at 429 grams, which is a good balance for performance and reliability in a Small Block Chevy application. This set is designed to be a direct replacement for your existing pistons, assuming your engine build aligns with the specified dimensions and compression ratio targets.

When installing this set, ensure your cylinder walls are properly honed to match the piston skirt design and that your connecting rods are balanced to the piston weight for optimal engine operation. Remember that this piston set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions for specific clearances and assembly procedures.
