SBC FT Piston Set 4.060 Bore -5.0cc

The SBC FT Piston Set 4.060 Bore -5.0cc from ICON PISTONS is engineered for serious small-block Chevrolet builds where compression ratio control and durability matter. These forged pistons are designed for street and strip applications where you need reliability under sustained boost or high RPM load. Whether you're building a carbureted hot rod, a naturally aspirated high-revving engine, or a forced-induction platform, this piston set delivers the engineering precision that separates a solid build from a short-lived one.

The -5.0cc dish on these forged pistons is a critical specification that reduces combustion chamber volume, allowing you to run tighter compression ratios without expensive head work. The 4.060-inch bore size accommodates over-bore applications, making these ideal for engine rebuilds where you've had to hone or re-sleeve the block. ICON PISTONS' forged construction provides superior material strength compared to cast alternatives, offering better resistance to detonation, thermal cycling, and the violent pressures of high-boost environments. The piston set weighs 10.6 lbs total, a specification that matters when balancing your rotating assembly for consistent engine dynamics.

This piston set is ideal for small-block Chevrolet engines—327, 350, and 383 displacements—where you're targeting compression ratios between 10.5:1 and 12:1 depending on fuel and ignition timing. Installation requires precise ring gap clearance, accurate bore honing to match the piston skirt clearance, and proper connecting rod sizing; work with an experienced machine shop if you're unfamiliar with bottom-end assembly. These pistons excel in vintage muscle car restorations, modern stroker builds, and any project where you demand reliability and controllable compression without the cost of custom high-compression forgings.
