Mahle MS Piston Set Chevy 358ci 4.035in Bore 3.500in Stroke 6.0in Rod .927in Pin -4cc 10.5 CR

Built from 4032 aluminum alloy, these Mahle MS pistons are designed for high-performance Chevy 358 cubic inch engines. The 4.035-inch bore size is a common specification for many performance builds, and the -4cc dish volume helps achieve a 10.5:1 compression ratio with a 3.500-inch stroke and a 6.0-inch connecting rod. This specific dish volume is a key design choice that balances power output with street drivability for many engine combinations.

Mahle uses a 4032 aluminum alloy for these pistons, which offers a good balance of strength and thermal expansion properties, making them well-suited for demanding applications where reliability is crucial. The pistons weigh in at 395 grams, which is a reasonable weight for a forged piston of this size, contributing to efficient engine operation. The 0.927-inch pin diameter is standard for many performance connecting rods, ensuring a solid connection between the piston and the crank assembly.

This set is intended for builders who know their way around a performance engine. While these pistons are well-made and designed for robust performance, remember they are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions for proper assembly and break-in procedures to ensure optimal performance and longevity of your engine build.
