SBF PowerPak Piston Set Inv. Dome 4.155 Bore

The SBF PowerPak Piston Set Inv. Dome 4.155 Bore from MAHLE PISTONS is designed specifically for small-block Ford enthusiasts who are building performance engines that require precision and durability. This piston set is ideal for street engines, weekend cruisers, or competition builds, providing the geometry and material quality necessary for high-performance applications.

The inverted-dome piston design enhances combustion efficiency by centering the flame front closer to the piston crown, which is particularly beneficial for stroker builds and high-compression applications. The 4.155-inch bore size ensures compatibility with stock or overbore small-block Ford blocks while maintaining the integrity of the ring groove design and pin boss strength.

Engine builders and machine shops working on 302, 347, 363, or 408-cubic-inch small-block Ford engines will find this piston set advantageous. The inverted-dome crown design should be paired with the appropriate cylinder head cc volume and spark plug location to maximize performance and efficiency.
