Mahle MS Piston Set SBC 358ci 4.030in Bore 3.480/3.500stk 5.7in Rod .927 Pin -5cc 10.4 CR Set of 8

This is a set of eight Mahle MS forged pistons designed for Chevrolet Small Block engines displacing 355 cubic inches. These pistons are built to handle performance applications, featuring a 4.030-inch bore and a -5cc dish that results in a 10.4:1 compression ratio when used with a 3.480 or 3.500-inch stroke crankshaft and a 5.700-inch connecting rod. Each piston weighs in at 474 grams, and they utilize a standard 0.927-inch wrist pin.

Mahle is a well-known name in engine components, and these pistons are constructed from 4032 aluminum, a material chosen for its strength and durability in high-performance engines. This alloy offers good thermal expansion properties, which helps maintain consistent piston-to-wall clearance throughout the engine's operating temperature range. The forged construction means these pistons are significantly stronger than cast pistons, making them a solid choice for builds that will see regular use or demand more power.

This set is intended for performance engine builds where increased compression and durability are key. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Ensure your engine assembly plans account for the specific dimensions and compression ratio these pistons will create.
