Cam Duration Vs Lift

Too many variables still,what do the heads flow at .400 ect.,also are the durations/lifts firgured with lash or without.Ive never seen a solid off the shelf with duration that small with that much lift or one with that much duration and that little of lift-and whats with a 113 lobe seperation?,those are not average grinds.A 113 spreads the power upstairs and if the heads are flowing considerably less at lower lifts then the big cam aint doin much good with the lack of lift so the small cam may actually make power in a more usable range depending on the combo,but the duration of the big cam helps to crutch the lack of lift/flow-kind of a wash but like I said alot of variables lol.
