Product Details

If you're building a high-performance Chevrolet Small Block engine, especially one targeting around 436 cubic inches, a solid set of pistons is crucial. This Mahle MS Piston Set is designed for that purpose, offering a well-built foundation for your engine's power output. These pistons are forged from 4032 aluminum, a material known for its strength and ability to handle the stresses of performance applications while maintaining good thermal expansion properties.

This set is engineered for a 4.165-inch bore and a 4.000-inch stroke, working with a 6.0-inch connecting rod. The -5cc dish volume contributes to a 12.4:1 compression ratio when paired with the right cylinder heads and gasket, which is a popular target for naturally aspirated performance builds seeking maximum efficiency and power. The included wrist pin measures 0.927 inches. Each piston weighs in at approximately 422 grams, contributing to a balanced rotating assembly.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete engine build, ensure you have the appropriate supporting components like crankshaft, connecting rods, and cylinder heads that complement this piston specification to achieve your desired performance goals.
