Mahle is well-known for its high-performance engine components, and this MS Piston Set for Big Block Chevy 460 cubic inch engines is a prime example of their commitment to quality. If you're building or rebuilding a performance Big Block Chevy, these pistons are designed to handle the demands of a high-output engine.

This set includes eight forged pistons, each featuring a 4.280-inch bore and designed to work with a 4.000-inch stroke and a 6.135-inch connecting rod. The pistons have a -3.4cc dish volume, which helps achieve a compression ratio of 8.2:1 when used with a standard deck height (9.800 inches) and appropriate cylinder heads. Each piston weighs in at 528 grams, a specification that contributes to balanced rotating assembly performance. The 0.990-inch pin diameter is standard for many performance applications.

These pistons are constructed from 4032 aluminum alloy, which offers a good balance of strength and lighter weight compared to cast pistons, making them suitable for performance builds. Please note that this piston set is not CARB approved and cannot be shipped to California. Always consult manufacturer installation instructions for proper assembly and break-in procedures.
