Can't get it to idle right! (Part 2)

I know this was a grude way to measure a cams lift, but is this cam as wild as it apears? I want this car to be a driver not a track star, if this is the case i think I'm going to switch out the cam. Again I knew very little about this motor when I got it because it was a good deal and I knew it wasn't perfect, it was in a beat up Duster and I think the person who built the motor was going to bracket race it.
