Select three Milwaukee-Eight camshafts and compare their intake and exhaust specifications side by side, in a compact stacked layout.
| Cam Selection | Valve | Lift (in) | Open (°) BTDC / BBDC | Close (°) ABDC / ATDC | Duration (°) | Overlap (°) | Lobe Center (°) | Lobe Sep (°) | Advance / Retard (°) |

Advance/Retard shifts the displayed opening, closing, and lobe-center events by the selected crankshaft degrees; duration, lift, overlap, and lobe separation remain unchanged. This is a hypothetical installed-cam timing adjustment, not a manufacturer specification. Opening/closing timing and overlap reflect the selected cylinder where available. Timing checking height may vary by manufacturer; do not assume these figures represent seat timing for dynamic-compression calculations.
Manual Cam Timing Calculator
Enter your own valve timing events in crankshaft degrees. Duration, overlap, intake/exhaust lobe centers, and lobe separation are calculated automatically. This does not change the three selected cams above.
Enter all four events measured at the same checking height. Use negative degrees when an event occurs on the opposite side of the stated reference (for example, intake opening 2° ATDC = −2° BTDC). Calculations assume a conventional four-stroke cam and are based on the supplied events; they do not verify manufacturer specifications. Lobe centers and LSA are derived from event midpoints and may differ from true maximum-lift centerlines for asymmetric lobes.
