Mahle MS Piston Set SBC 361ci 4.05in Bore 3.500in Stroke 6.0in Rod .927in Pin -4cc 10.7 CR Set of 8

These Mahle MS Series pistons are forged from 4032 aluminum, a material chosen for its strength and ability to handle the heat and stress of performance engines. With a 4.050-inch bore and a -4.1cc valve relief, they are designed to work with a 3.500-inch stroke crankshaft and a 6.000-inch connecting rod, creating a 361 cubic inch displacement for your Small Block Chevrolet. The 0.927-inch wrist pin diameter is standard for many performance applications.

The design of these pistons results in a 10.7:1 compression ratio when paired with the correct cylinder head volume, making them a solid choice for naturally aspirated or forced induction builds where you want a noticeable power increase without going too extreme. Each piston weighs in at approximately 400 grams, which is a good balance for durability and rotational mass in a performance street or strip engine. Mahle is a well-known name in engine components, and this set reflects their commitment to well-built parts for demanding applications.

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 a good idea to consult your engine builder or a trusted mechanic to ensure these pistons are the right fit for your specific build goals and to confirm all necessary supporting components, such as rings and bearings, are compatible.
