Mahle MS Piston Set Ford 514ci 4.44in Bore 4.150in Stroke 6.7in Rod 0.990 Pin -28cc 9.9CR - Set of 8

Mahle is a well-known name in engine components, and their MS Piston Set is built for serious Ford Big Block builds. If you're working on a 514 cubic inch Ford engine, these pistons are designed to handle the demands of a performance rebuild. They feature a 4.44-inch bore and are paired with a 4.150-inch stroke, working with a 6.7-inch connecting rod and a 0.990-inch wrist pin. This combination is key for achieving the correct compression and stroke for your engine's intended performance profile.

These pistons are forged from 4032 aluminum, a material chosen for its strength and durability under high temperatures and pressures, while also offering good thermal expansion properties. They have a -28cc dish volume, which, combined with the other engine dimensions, results in a 9.9:1 compression ratio. This is a solid compression target for many naturally aspirated or forced induction performance applications, offering a good balance between power and pump gas compatibility. Each piston weighs approximately 560 grams, contributing to a well-balanced rotating assembly.

This set includes eight pistons, enough for a complete V8 engine. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
