About this part

Product Details

This Mahle MS Piston Set includes eight forged pistons, designed for Ford 349 cubic inch engines. These pistons feature a 4.040 inch bore and are built to work with a 3.400 inch stroke and a 5.400 inch rod, utilizing a 0.927 inch pin. The dish volume is -6.5cc, resulting in a 10.1 compression ratio when installed in the specified engine configuration.

Mahle uses 2618 aluminum alloy for these pistons, a strong material commonly chosen for high-performance applications due to its durability and resistance to expansion under extreme heat. Each piston weighs approximately 415 grams, contributing to a well-balanced rotating assembly. This set is a solid option for engine rebuilds where enhanced performance and reliability are key goals, offering a significant upgrade over stock components for those looking to push their Ford Small Block engine further.

When rebuilding your engine with these pistons, ensure you follow the manufacturer's specifications for ring gap, bearing clearance, and piston-to-wall clearance to achieve optimal performance and longevity. This set is intended for competition or off-road use and is not CARB approved, meaning it cannot be shipped to California.
