I found your "lack of gas" thread.
One more thing before moving on. When you pull the vacuum hose from the vacuum advance (when checking timing) does timing jump back and the engine slow down? If so that's good. Just want to make sure that the vacuum diaphragm on the distributor is OK.
The vacuum gauge should be hooked up to any manifold vacuum source. Since you have the vacuum advance connected to the manifold you can tee it into this hose.
Regarding the engine quitting when you put the car in gear- if you have the PVC hooked up properly and there are no major vacuum leaks, timing is set properly, and it is firing on all cylinders then it sounds like a carb problem. Assuming that the Edelbrock has a big enough idle circuit for your cam (I have no experience with Edelbrock) then the idle speed and mixture screws probably just need some adjusting. Having the vacuum gage connected will help with this.
Yes the engine needs to be warmed up and the choke disengaged to get good vacuum readings and to make carb adjustments.
