Mahle MS Piston Set SBC 384ci 4.040in Bore 3.750in Stroke 5.7in Rod 0.927 Pin -16cc 9.9 CR Set of 8

This Mahle MS Piston Set includes eight forged pistons designed for a Chevrolet Small Block 385 cubic inch engine. These pistons feature a 4.040-inch bore and a 3.750-inch stroke, paired with a 5.700-inch connecting rod and a 0.927-inch pin. The -16cc dish volume contributes to a 9.9 compression ratio, and each piston weighs 463 grams. They are constructed from 4032 aluminum, a material known for its strength and durability in high-performance applications.

Mahle's MS series pistons are built for demanding engine builds where reliability and performance are key. The 4032 aluminum construction offers excellent thermal expansion properties, which helps maintain piston-to-wall clearance as the engine heats up, reducing noise and wear. This is particularly important for engines that will see frequent use or higher performance demands. The -16cc dish is engineered to work with specific head chamber volumes to achieve the target 9.9 compression ratio, making these pistons a solid choice for builders looking for precise engine tuning.

When installing these pistons, ensure you follow the manufacturer's recommended clearances and procedures for optimal performance and longevity. Remember that these pistons are not CARB approved and cannot be shipped to California. Always consult your engine builder or Mahle's technical documentation for specific installation guidelines and compatibility with other engine components.
