SBF Magnum Hyd. Roller Cam 260HR

The COMP Cams SBF Magnum Hydraulic Roller Cam 260HR (part number 31-412-8) is a purpose-built camshaft engineered for small block Ford engines seeking moderate lift and duration with reliable hydraulic roller actuation. This camshaft delivers 0.480 inches of lift on both intake and exhaust, with a symmetrical 260-degree duration and 110-degree lobe separation angle, calibrated to produce usable power across a broad 1200–4500 RPM band.

The hydraulic roller design minimizes valve train stress and wear compared to mechanical lifter systems, while the 260HR profile balances street responsiveness with modest peak power gains. The 110 LSA (lobe separation angle) provides overlap characteristics suitable for stock-to-modified engine combinations without requiring aggressive tuning or custom fuel mapping. Hydraulic roller cams automatically compensate for thermal expansion and wear, eliminating the need for manual valve adjustments and reducing maintenance frequency in service.

This camshaft is specified for small block Ford applications and suits rebuilds, performance upgrades, and restorations where improved response is desired without departing significantly from original engine characteristics. The moderate lift and duration make it compatible with stock intake manifolds, cylinder heads, and valve train geometry, reducing the need for supporting modifications.

COMP Cams is recognized in the performance engine market for precision cam grinding and quality control, and this 260HR profile represents a proven design for small block Ford powerplants seeking reliable, mid-range performance without extremes in idle quality or fuel consumption.
