If I understand correctly, you are saying that having a higher peak lift would allow for a longer duration at let's say .200 lift and have the same or almost the same .050 duration. From looking at Crane's and Comps lobe chart,that seems like what happens.I of course have no data to back me up other what I read.Oneof the advances in cam design seems to be fast opening and closing rates along with higher total lift for a larger "curve" but keeping total duration low to help with low speed torque for a given duration. For myself I am looking for low speed cylinder pressure to make the engine seem bigger in normal driving. I still want some improvement in top end,which should be easy to do given the specs for the stock cams. Jay
