SBF 351W Solid Cam 280B-6

The Comp Cams SBF 351W Solid Cam 280B-6 is a mechanical flat tappet camshaft engineered for oval track racing on small block Ford engines. This purpose-built cam delivers the aggressive valve timing and lift profile required for high-RPM competition performance in short-track racing applications where controlled aggression and repeatability are non-negotiable.

The SBF 351W features 0.541-inch intake lift and 0.522-inch exhaust lift with a 280/284-degree duration split, optimized for the narrow powerband oval track engines require. The 106-degree lobe separation angle (LSA) tuning creates a specific torque curve biased toward mid-range response rather than peak power, a critical advantage when racers must manage variable track conditions and fuel formulations. The 3000–6500 RPM operating range reflects the practical powerband constraints of small block Ford applications in stock-class racing, where engine limitations and fuel restrictions demand precise cam selection rather than all-out peak performance chasing.

This cam is purpose-built for racers competing in classes where small block Ford engines dominate—local short tracks, regional oval racing sanctioning bodies, and heritage bracket racing where engine rules restrict displacement and modification pathways. Mechanical flat tappet design requires precise valve clearance adjustment and routine maintenance, making it suited for dedicated competitors with access to dyno tuning and ongoing engine management rather than casual street applications. Comp Cams' manufacturing standards ensure the lift and duration specifications remain consistent across the RPM range, critical for repeatable performance week to week on the track.
