I had the gauge on earlier this summer and if I remember its around 12" right now. That cam doesn't help. I even tried a different power valve in a Holley street avenger to help. I ended up going to to new, smaller edelbrock, which seemed to help a bit.

Both those carbs had the idle issue. I'm set up right now with a lokkar pedal and cable for the throttle. It seems loose enough, so does the linkage on the carb it self.
