The Mahle MS Piston Set for Small Block Chevy engines is engineered for high-performance applications with a 357 cubic inch displacement. Each piston features a 4.040-inch bore diameter, designed to provide precise fitment and optimal combustion efficiency. The pistons are crafted with a 3.480/3.500-inch stroke configuration and are paired with 5.700-inch connecting rods for a robust and reliable engine build. The 0.927-inch piston pin ensures secure attachment, while the set offers a compression ratio of approximately 10.4:1, ideal for street performance and moderate racing conditions. Constructed with high-quality materials and coatings, including phosphate and Grafal, these pistons are built for durability and long-lasting performance in demanding environments. The set includes eight pistons, making it suitable for complete engine rebuilds or upgrades. Each piston weighs around 478 grams, contributing to balanced engine dynamics and smooth operation. The Mahle MS Piston Set features design attributes that meet the requirements of high-performance small block Chevy engines, providing excellent compression and power output while maintaining structural integrity under stress. Please note, these pistons are not carb-approved and require acknowledgment of carb compliance before installation. They are not suitable for EPA-regulated applications but are ideal for enthusiasts seeking reliable, high-quality components for performance upgrades. Built with advanced coatings such as phosphate and Grafal, these pistons resist wear, reduce friction, and improve longevity, ensuring your engine performs at its best over time. Whether you’re rebuilding or upgrading your engine, the Mahle MS Piston Set offers precision engineering and durability necessary for a successful project.
