SBC FT PowerPak Piston Set 4.030 Bore -2.0cc

The SBC FT PowerPak Piston Set 4.030 Bore -2.0cc is engineered for serious Small Block Chevrolet builders targeting high-performance street and competition engines. Built by MAHLE PISTONS—the industry standard for OEM and aftermarket reliability—this piston set addresses the core requirement of any stroker or overbore build: precision bore sizing and compression geometry tuned for maximum efficiency and durability. Whether you're upgrading from factory pistons or rebuilding a damaged short block, this forged piston set delivers the strength and thermal stability needed for sustained power delivery.

The -2.0cc bowl volume reflects a modern compression-optimized design that works with stroker cranks and aftermarket cylinder heads to achieve elevated compression ratios without excessive piston-to-valve clearance concerns. MAHLE's forged construction resists detonation and thermal cycling, critical for turbocharged, supercharged, or nitrous applications where commodity cast pistons fail. The 4.030" bore specification means these pistons are sized for overbored blocks—typically bored 0.030" over stock 4.000" diameter—or direct fitment in existing 4.030" blocks. The -2.0cc dish reduces combustion chamber volume, sharpening the burn profile and improving fuel economy and throttle response on naturally aspirated engines, while supporting forced-induction tuning on boosted platforms.

This piston set suits engine builders and mechanics upgrading tired 350, 383, or 406 cubic-inch Small Block builds where stock or low-quality pistons no longer meet power targets or reliability standards. Installation requires matching rings, rod selection, and bearing clearance verification—standard machine-shop procedures for any serious rebuild. Confirm your block bore diameter and final compression ratio target before purchase; improper bore sizing or ring gap tuning will result in blow-by, oil consumption, or catastrophic failure. The set's 11.16 lb weight is typical for a full eight-piston assembly and reflects the forged alloy's density and durability.
