BBC FT Power-Pak Piston Set 4.280 Bore -3.4cc

The BBC FT Power-Pak Piston Set 4.280 Bore -3.4cc is a precision forged solution designed for serious big block Chevrolet engine builders and street/strip enthusiasts. This piston set is engineered for high-performance BBC applications where reliable ring sealing, thermal stability, and consistent compression are essential. Whether you're assembling a mild stroker package or a full-competition engine, quality pistons are crucial for reliable power delivery and engine longevity.

MAHLE's FT Power-Pak line features advanced forged aluminum alloy construction, optimized skirt profiles, and ring groove geometry to effectively manage combustion pressures and minimize piston rock in the bore. The 4.280-inch bore specification ensures a precise fit in properly honed BBC blocks, while the -3.4cc dish cavity is strategically designed to control compression ratios in stroker or modified combinations. This design balances low-friction characteristics with durability, using thermal-resistant materials and piston pin boss reinforcement to withstand sustained high-RPM operation.

This piston set is particularly beneficial for builders planning high-performance applications, especially in forced-induction setups. The -3.4cc dish geometry makes it valuable for tuning compression ratios, ensuring compatibility with various engine configurations. Builders can expect enhanced performance and reliability in demanding operating conditions, making this piston set an excellent choice for serious enthusiasts.
