SBF FT PowerPak Piston Set 4.030 Bore -6.5cc

The SBF FT PowerPak Piston Set 4.030 Bore -6.5cc from MAHLE PISTONS is designed specifically for Small Block Ford enthusiasts and engine builders. This piston set is essential for those looking to enhance performance in naturally aspirated applications while ensuring reliability and precision-engineered internals. Whether you are rebuilding a classic 5.0 or modernizing a vintage Ford engine, this piston set is a critical component for achieving durability and optimal performance.

MAHLE's engineering emphasizes optimized ring design, controlled expansion rates, and precision skirt geometry to minimize friction and side-wall slap, which are vital for longevity under sustained RPM loads. The 4.030-inch bore specification is suitable for overbore block configurations commonly found in street and race SBF builds. The -6.5cc dish is designed to help achieve a specific compression ratio when paired with compatible cylinder heads and gasket thickness.

This piston set is particularly beneficial for builders focused on naturally aspirated engines, but it can also be adapted for supercharger applications with the right engine modifications. The FT (Forged Truck) designation indicates high-strength forged construction, making these pistons resistant to detonation and thermal stress. This quality makes them suitable for use with both pump gasoline and race fuel, ensuring reliability in vintage drag or road-race builds.
