This Mahle MS Piston Set is built for Ford SBF (Small Block Ford) engines displacing 449 cubic inches. You get a complete set of eight forged pistons, each designed with a 4.100-inch bore and a 4.250-inch stroke, paired with a 6.700-inch connecting rod and a 0.990-inch wrist pin. These pistons feature an 18cc dish volume, which helps achieve a 10.0:1 compression ratio with the specified components. Each piston weighs approximately 500 grams, balancing strength and weight for performance applications.

Mahle utilizes 4032 aluminum alloy for these pistons, a material known for its strength and durability, making them well-suited for demanding engine builds. The forged construction provides a solid foundation, offering improved resistance to the stresses of high-performance operation compared to cast pistons. This set is engineered to work with a 4.250-inch stroke crankshaft and a 6.700-inch connecting rod, ensuring proper geometry and fitment within the engine block. The 0.990-inch wrist pin diameter is a common size for performance applications, offering a strong connection between the piston and connecting rod.

This piston set is a key component for anyone rebuilding or upgrading a Ford FE engine to 449 cubic inches.
