I’ll take question and comments yes
Okay.
From the flow chart we are seeing essentially a shift in flow away from low lift and toward better high lift flow.
I am using .354" figure as max valve lift with S&S cams.
It is doing real well at .250" and higher.
There is a significant drop of 10 cfm at .100" lift.
Not too concerned about the smaller drop at .050" because not much flow is happening yet.
Your average flow over the working lift curve is only 2cfm over stock. If you could pull up that dip at .100", you could increase the average flow to 4cfm over stock.
Do you have any cause isolated for the drop at .100" lift?
At what lift does the valve clear the short side chamber wall by .200"? Maybe there might be some shrouding by the chamber wall at low lift, but clears out as the valve moves further clear of the chamber wall?
