Mahle MS Piston Set Chevy 358ci 4.035in Bore 3.500in Stroke 5.7in Rod .927in Pin -4cc 10.5 CR

This Mahle MS piston set is built for Chevrolet Small Block engines displacing 358 cubic inches. If you're rebuilding a performance engine or looking to get more out of your classic Chevy, these pistons are a solid choice for handling increased power and stress. They feature a 4.035-inch bore and are designed to work with a 3.500-inch stroke crankshaft and a 5.700-inch connecting rod, with a .927-inch wrist pin diameter.

Mahle uses a 4032 aluminum alloy for these pistons, which is well-suited for high-performance applications due to its strength and thermal expansion properties. This material helps ensure the pistons can withstand the heat and pressure generated in a performance engine. The pistons have a -4.1cc dish volume, which, when combined with the other engine components, results in a 10.6:1 compression ratio. This compression level is ideal for naturally aspirated performance builds that use premium pump gas, offering a good balance between power and drivability. Each piston weighs approximately 431 grams, contributing to a balanced rotating assembly.

This set is designed as a direct replacement for specific Chevy Small Block configurations. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Ensure you have the correct connecting rods and crankshaft to match the specifications for a proper installation. For optimal performance and longevity, always follow the manufacturer's recommended installation procedures and clearances.
