SBC FT PowerPak Piston Set 4.030 Bore -4.1cc

The SBC FT PowerPak Piston Set 4.030 Bore -4.1cc from MAHLE PISTONS is designed for small-block Chevrolet builders who demand high-performance internal engine components. This piston set is ideal for both forced-induction and naturally aspirated applications, whether for street use or competition. It provides the durability and power delivery needed for serious horsepower gains and extended engine life.

MAHLE's FT PowerPak line utilizes advanced forging technology, featuring optimized ring grooves and compression geometry to withstand the stresses of boost and detonation. The 4.030-inch bore specification accommodates overbored or stroked SBC platforms, allowing for increased displacement while maintaining structural integrity. The -4.1cc dish design effectively reduces compression chamber volume, aiding in tuning compression ratios for modified engines.

This piston set is compatible with small-block Chevrolet engines ranging from 262 to 383 ci in displacement, making it an excellent choice for builders upgrading from stock cast pistons to forged performance components. Proper installation requires verification of clearances, ring gapping, and professional machine work to ensure accurate bore specifications.
