Well, with using a centrifugal blower like a Novi, there is some lag also.
So it does not fill the cylinders like a roots/screw type supercharger.

As far as lobe center,,, it idles pretty crazy & this was when I had three DCOE Webbers (which,by the way), makes your engine run really smooth as compared to a single four barrel carb.

With a cam having these specs in a 250 CI engine,even a cam w/a 118 lobe center will idle rough,it is a pretty big cam for running on the streets.

I choose a wide lobe center as to get some kind of desent idle & I wanted it to pull really hard on the top end,which it did.

If you bought a cam with roughly the sam specs w/a 110 lobe center,you will be blowing boost pressure out of your exhaust(causing lower boost)
It will idle really bad plus you will be losing a lot of down low grunt. Your cranking cylinder pressure will be low.

I have bigger valves, 1.88-1.90"IIRC intake & a 1.60" exhaust
