Mopar 383 help please

No, Im not sure. I put the gauge on the only vacuum port on the bottom of my carb.

It doesnt have power brakes. No pcv valve.

Its been like this and has not changed since I replaced the stuff. Only difference is now it starts, runs and even revs to high rpm.

Not sure what its idling at RPM wise cuz I dont have a tach but it sounds normal. However sometimes it gets stuck at a high rpm. Almost like the carb isnt coming off of fast idle once warm. Had that happen when I drove it. Also, it doesnt have the power a 383 should have. That noise I talked about gets annoying loud when I give it gas. Revs up but not a whole lot of power.

If your serious on helping me I can take a good quality video and post it up.
