My only other question is the vacuum from the edelbrock carb, should I use the ported vacuum (no vacuum at idle) or the full vacuum?
Thanks again,

That will be your choice and also tied to how your engine is built. If you are looking at getting your total advance in early, then use the non-ported orifice and if you are running basically stock, then you can go with the ported orifice. I am running mine on my stroker motor and my son's 350 on the non-ported outlet and that is because I bring in the timing advance early on the HEIs that I am using.
