SBF Flat Top Piston Set 4.040 Bore -5cc

The SBF Flat Top Piston Set 4.040 Bore -5cc from Sportsman Racing Products is a forged piston set designed specifically for Small Block Ford engines that require precise bore specifications and a negative dome compression. This eight-piece set is ideal for both recreational boaters and serious offshore operators looking to rebuild or upgrade their marine powerplants.

Each piston features a 4.040-inch bore diameter and is constructed with a flat-top design that minimizes combustion chamber turbulence, enhancing thermal efficiency under sustained load. The negative dome volume of -5.00 cc effectively reduces combustion chamber volume, which is crucial for applications that require detonation resistance or boost tolerance.

This piston set is compatible with cast-iron block Small Block Ford marine engines, ensuring that users can restore original compression and combustion characteristics. Whether servicing a well-used fishing platform or upgrading a repowered inboard installation, the precision forging of these pistons guarantees reliable performance and stability.
