Engine Surging in slow traffick
My engine is a 350 Chevy engine, and it has a B&M Street Blower (5lbs boost) with a Holley manifold referenced power valve.
The problem I am having is that if I am in stopped traffic for a period of time (i.e. a rod run consisting of 5000 participants, and stopped or moving 1-2mph for 5 minutes)...when traffic then picks up the engine surges. For example, it's as if I were pushing the pedal, letting up, pushing, letting up. This happens until I get moving to 30 mph for a few seconds then clears up.
One thing I am sure of is that it is getting quite hot under the hood...and when I get moving the air flow relieves that heat. I expect it is heat related.
That being said, I'm not sure in what way.
Any thoughts?Thanks

Good to have her home finally, still need to go back and give her another polish after messing with the engine stuff. Made it up to Idaho. Also a local show.
