Ignore the ignorance of post #8.
From the specs, you have one of those Bootlegger/Muthathumpa/Whiplash/Bumrush cams which as a very poor choice for a street car. They were designed to impress the drive-in crowd with the rowdy exh.
The problem is the cam, not the carb. The carb is just showing up the problems you get with a cam that has a lot of overlap.
I suspect the idle vac is only going to be 10-12", so the stock PCV will be unlikely to work reliably. If it is removed & blocked, pri blades on the carb need to be opened further [ more later on this ] to compensate for the air that the PCV would normally provide. Two choices here, buy an adj PCV [ such as a Wagner ] or gut the stock PCV & braze/weld in a plate with a 7/64" orifice [ this duplicates the flow area of a stock PCV at idle ].
Once the decision is made about the PCV, carb should be removed to check the T slot. At idle, should be about 0.040" of slot showing. I expect it to be much more, which is causing your stumble. In the Edel Owners manual, the section on low vac cams recommends plenty of initial timing &/or using vac adv
connected to manifold vacuum to do this.
Very simple first step reqd here: with engine idling, loosen dist clamp & SLOWLY turn dist CW [ this advances timing ]; stop when you get smoothest idle/highest rpm; check what the timing is & report back.
Below is from a Holley carb book. It talks about idle timing of 50* BTDC!! Think about why idle timing isd talked about in a carb book.....& in more than one place.
