Product Details

If you're rebuilding the engine in your Ford Small Block 364 cubic inch application, a solid set of pistons is crucial for performance and reliability. This Mahle MS Piston Set is built for those who demand more from their engine, whether it's for street performance or track use. These pistons are designed to handle the stresses of a performance build, ensuring your engine runs strong.

Mahle uses 2618 aluminum alloy for these pistons, a material known for its strength and durability under high temperatures and pressures. Each piston has a -6.5cc dish volume, contributing to a 10.4:1 compression ratio when paired with the specified stroke and rod length. The 4.125 inch bore size is standard for this application, and the 1.090 inch ring groove height is designed to work with modern piston ring sets. They also feature a .927 inch pin diameter, a common size for performance connecting rods. At 423 grams each, these pistons offer a good balance of strength and weight for a performance rotating assembly.

This set includes eight pistons, ready for installation into your Ford Small Block. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to manufacturer installation instructions for proper assembly and break-in procedures.
