This Mahle MS piston set is designed specifically for Chevrolet small block engines with a 357 cubic inch displacement. Crafted from high-quality materials, these pistons feature a 4.040-inch bore diameter, providing precise fit and optimal performance for engine rebuilds or upgrades. The pistons are engineered with a stroke of 3.480 to 3.500 inches, complemented by a 5.700-inch connecting rod length, ensuring smooth operation and durability under demanding conditions. The 0.927-inch pin and -5cc compression height are optimized for performance tuning, supporting a compression ratio of approximately 10.3:1 for a balanced mix of power and efficiency. Weighing approximately 499 grams per piston, these components contribute to a lightweight yet robust engine assembly, suitable for street or racing applications.
Manufactured by Mahle, these pistons feature advanced coatings such as phosphate and Grafal to enhance wear resistance and reduce friction, thereby extending engine life and improving overall reliability.
