SBF PowerPak FT Piston Set 4.155 Bore -6.5cc

The SBF PowerPak FT Piston Set 4.155 Bore -6.5cc is a forged competition-grade piston assembly designed specifically for small-block Ford engines. This product is aimed at serious engine builders and performance enthusiasts who are looking to rebuild or upgrade their engines for applications such as street driving, bracket racing, or extended dyno sessions.

Manufactured by MAHLE PISTONS, these forged aluminum units utilize proprietary metallurgy that enhances their ability to withstand detonation, thermal shock, and the mechanical stresses associated with aggressive valve timing. The -6.5cc dome configuration is essential for tuners aiming for precise compression ratio control and optimized combustion chamber volumes when matched with specific cylinder head and block combinations.

Builders will find the SBF PowerPak FT Piston Set most beneficial when their engine blocks are bored to the 4.155-inch specification, as the negative dome volume provided by this set is crucial for achieving desired compression ratios. This piston set is ideal for those looking to enhance performance while ensuring reliability under high RPM conditions.
