Description

The Mahle MS Piston Set designed for Small Block Chevy engines offers precise engineering for optimal performance. Each piston features a 4.040-inch bore and a 3.875-inch stroke, tailored for a 397 CID engine configuration. Crafted from high-quality materials, these pistons provide durability and reliable operation under demanding conditions. The set includes eight pistons with a 0.927-inch pin diameter, ensuring a secure fit within the engine assembly.
