I also still hear a air nose from somewhere.
I cannot find anything online about vacuum lines so I thought I would come here for a last resort and I know you all know. If anyone could help possibly a picture or video of all the vacuum lines and if they should be open or closed up, Thank you all so very much.

Well your vaccum lines should not be too hard to figure out. Off the top of my head I can list some lines. Your gonna need one on the vaccum advance, pcv, one down to the trans, vaccum modulator I think is what that is called. May cause some problems with shifting if that is not hooked up. You also have one going to the brake power booster. I know not very specific but gives ya an idea of what should have a line running to it. Cannot think of anymore right now, those are just off the top of my head.

You need to put a cap over that or better yet get rid of it altogether and since it looks like it has 2 other hoses that are plugged hooked into it. I looked at some of your other pictures. Did you ever hook the line going from under the front of your carb over to the oil breather on your D side valve cover?
