Mahle MS Piston Set SBC 358ci 4.030in Bore 3.480/3.500stk 6.0in Rod .927 Pin -5cc 10.4 CR Set of 8

Mahle is a well-known name in engine components, and this Mahle MS Piston Set is built for serious performance applications. If you're rebuilding a Chevrolet Small Block engine, especially one around the 355 cubic inch displacement, these pistons are designed to handle the demands of a high-compression setup. They feature a 4.030-inch bore and are engineered to work with a 3.480 or 3.500-inch stroke crankshaft and a 6.000-inch connecting rod, with a standard .927-inch wrist pin.

These pistons are forged from 4032 aluminum, a material chosen for its strength and durability under high temperatures and pressures. The -5cc valve relief dish contributes to a calculated compression ratio of 10.4:1 when used with a typical 64cc combustion chamber, making them suitable for naturally aspirated or forced induction builds where improved power is the goal. Each piston weighs in at 438 grams, which is a good balance for strength and rotational mass in a performance engine. This set includes all eight pistons needed for a complete engine build.

Please note that these pistons are not CARB approved and cannot be shipped to California. They also carry a Prop 65 warning. Ensure you consult with your engine builder or refer to detailed build specifications to confirm compatibility with your specific engine combination and desired performance goals.
