This set is specifically for 348 cubic inch engines, featuring a 4.037-inch bore and a 3.4-inch stroke, paired with a 5.4-inch connecting rod and a .927-inch pin. These pistons are crafted from 4032 aluminum, a well-known material for its strength and thermal expansion properties, making them suitable for demanding sealed race engine applications. The -6.5cc dish volume contributes to a 10.0:1 compression ratio with the specified components, offering a solid foundation for a powerful build.

Mahle has a strong reputation for producing well-built engine components, and this piston set is no exception. The 4032 aluminum construction means these pistons can handle the heat and stress of a performance engine. Each piston weighs in at 404 grams, providing a consistent and balanced rotating assembly. This set includes all eight pistons needed for a V8 engine, ensuring you have the core components for your engine rebuild. Remember, these pistons are intended for sealed race engines and are not CARB approved, meaning they cannot be shipped to California.

When undertaking a performance engine build of this caliber, attention to detail is key. Ensure all supporting components, such as crankshaft, connecting rods, and cylinder heads, are compatible with these pistons to achieve the desired compression ratio and performance. Proper balancing of the rotating assembly is also crucial for engine longevity and smooth operation. This Mahle piston set is a well-made choice for enthusiasts looking to maximize the potential of their Ford Small Block engine.
