BBF 460 D-Cup Piston Set 4.90 Bore +22cc

The BBF 460 D-Cup Piston Set 4.90 Bore +22cc is engineered for serious big-block Ford performance builders seeking maximum displacement and compression in their 460 cubic-inch engines. KB Performance Pistons designs these forged units specifically for high-RPM applications where durability and precise tolerances are non-negotiable. Whether you're building a street performance engine, competition drag setup, or marine application, this piston set delivers the reliability and strength required for sustained power output and longevity under demanding conditions.

Each piston in this set features a 4.90-inch bore diameter matched to the +22cc dome chamber, which elevates compression ratio and promotes faster, more efficient combustion—critical for extracting peak horsepower from a naturally aspirated or boosted 460. The D-Cup design incorporates proven ring geometry and pin offset that minimize friction, reduce skirt-to-wall wear, and optimize load transfer during the power stroke. KB Performance's forged construction resists detonation and provides the structural integrity necessary for sustained high-boost environments, while precision-machined wrist pins and superior piston-to-rod clearancing ensure smooth, quiet operation across the entire RPM band.

This piston set is ideal for engine builders, performance shops, and enthusiasts assembling or rebuilding 460 cubic-inch big-block Ford engines for street, strip, or marine duty. Proper installation requires attention to ring gap clearance, bore honing to specification, and verification of piston-to-deck clearance before final engine assembly. Always verify compatibility with your specific connecting rods, cylinder head gasket thickness, and intended compression ratio before ordering, as the +22cc dome geometry directly impacts final engine specifications and tuning requirements.
