OK, thanks. Just curious on this one. One has to just guess on the Hughes cams' advertised durations since they don't give the numbers. Guessing 48* longer than .050" lift duration, your DCR works out to around 8.0 at sea level but drops to 7.4-7.5 at 3000' of elevation. So that is a significant drop in DCR, and is helping you stay away from detonation-land.
