318 Motor, please help

FOR THE WIN!!!! I just got home, practically ran my wife over to head out to the garage and try this out. i pulled off the breather with the hose attached, crewed on a basic oil cap for now and plugged the hole on the back of the carb. fired it up, dropped it into gear without even letting it warm up and it stayed running!!! now i know there has been a vacuum leak this whole time so all my tweaking has been for not. now i can start all over and get this bad boy running strong. i cant believe i didn't think of this. i'll be going to NAPA tomorrow for a PVC valve. Thank you Bobzilla!!! Thank you everyone else for the help, ill keep you posted. and no.....i wont get rid of my Holley, i think they look 10x better than the Edelbrock and much more tunability.
Out of curiosity, whats the vacuum reading at idle now? :)

Only thing I have to say about Holley is the gas needle drops pretty quick other than that I have no issues with Holley or Eddy or carter etc.
