Mahle MS Piston Set BBC 632ci 4.600in Bore 4.75in Stroke 6.66in Rod 0.990 Pin -3cc 10.8 CR Set of 8

If you're building a serious performance engine, Mahle's MS Piston Set for Big Block Chevy (BBC) applications is a solid choice. This set is designed for 632 cubic inch engines with a standard deck height, featuring a 4.600-inch bore and a 4.75-inch stroke. These pistons are crafted from 4032 aluminum, a material known for its strength and ability to handle high temperatures and pressures, making them well-suited for demanding builds.

Each piston in this set has a -3cc dish volume, which, when paired with the specified bore and stroke, results in a 10.8:1 compression ratio. This compression level is ideal for naturally aspirated performance applications where you want a good balance of power and pump gas compatibility. The pistons come with a 0.990-inch pin diameter, a common size for performance connecting rods, and a rod length of 6.66 inches is recommended for optimal geometry. Mahle is a well-known name in engine components, and this piston set reflects their commitment to well-built parts for high-performance engines.

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. They also carry a Prop 65 warning. Ensure you have the correct connecting rods and crankshaft to match the specifications for a successful engine build.
