SBF F/T Piston Set 4.030 Bore -7cc

The SBF F/T Piston Set 4.030 Bore -7cc by WISECO-PRO TRU is engineered for small-block Ford builders seeking maximum compression and power in high-performance or racing applications. This forged piston set delivers the precision geometry and material science required for serious engine builders, whether you're assembling a street performance engine, bracket racing powerplant, or full competition build. The -7cc dome compression design targets engines running premium fuel and aggressive cam profiles where effective static and dynamic compression ratios demand careful calculation.

WISECO-PRO TRU pistons are manufactured from premium forged aluminum alloy, providing superior strength-to-weight ratio and thermal stability under extreme combustion pressures. The 4.030-inch bore size accommodates over-the-top engine blocks or factory blocks bored to near-maximum limits, allowing you to maximize displacement without sacrificing the integrity of cylinder walls. The -7cc dome profile increases combustion chamber volume strategically, making this set ideal for forced-induction applications, nitrous oxide systems, or engines where detonation control and margin of safety are non-negotiable—particularly important in turbocharged or supercharged small-block Ford combinations.

This piston set is essential for engine builders modifying 289, 302, 347, or 408 cubic-inch small-block Ford platforms where bore sizes exceed stock specifications. Proper ring end-gap clearance and pin-fit verification during assembly are critical to long-term reliability; consult your engine builder or WISECO technical resources before installation. The set's weight and dimensions support installation in standard small-block Ford blocks with appropriate rod lengths and crank throws, making it compatible with both carbureted and fuel-injected platforms when compression ratios and fuel octane ratings are matched correctly.
