SBF FT Piston Set w/TWH 4.030 Bore -3.8cc

The Race Tec Pistons SBF FT Piston Set with Twisted Wedge Head for 4.030 Bore, -3.8cc delivers precision-engineered forged pistons purpose-built for Small Block Ford applications demanding high-revving performance and durability. This eight-piece piston set combines flat-top geometry with the proven Twisted Wedge combustion chamber design, optimizing flame travel and burn efficiency across the RPM range. Race Tec's forged construction provides the strength needed for sustained boost pressure, high-RPM operation, and repeated thermal cycling without deformation.

The -3.8cc dish volume is engineered to achieve specific compression ratios when matched with your cylinder head and gasket stack, a critical variable for forced-induction and naturally aspirated builds targeting maximum efficiency and ignition timing control. The 4.030-inch bore specification fits overbored Small Block Ford blocks and works in conjunction with the 1.5 x 1.5 x 3.0mm ring groove dimensions to maintain proper seal and minimize blow-by across load conditions. Forged pistons inherently offer superior fatigue resistance compared to cast alternatives, especially when engine internals are subjected to repeated high-load cycles.

This piston set is targeted at SBF engine builders and performance enthusiasts constructing stroker builds, turbocharged engines, and dedicated race platforms where reliability and repeatable combustion are non-negotiable. The flat-top design minimizes valve-to-piston clearance interference while maintaining combustion chamber volume control, making this set compatible with both stock and ported cylinder head options. Whether assembling a street/strip dual-purpose engine or a dedicated competition platform, this Race Tec Pistons product provides the engineering foundation for confident high-RPM operation.
