Does anyone know were I can post this question and get some discussion. I checked the Corvette LS7 titanium valve specifcations and they are running .331" lift with 1.8 rockers total lift .590" , 101 lbs. spring pressure @ 1.95" installed height 310 lbs. @ 1.37" open using roller hydraulic lifters. I have found on a flat tappet mechanical cam with 1.5 rockers with 2.08 intake steel valves that I need around 150 closed - 450 open to allow the valve to open and close without float to around 7200 - 8200 rpm. I guess I'm just going to do it and find out as usual.
