I have a holley on my 67 289 2v and is making the engine surge with 1 second interval at idle.
The first question is where to find out model number.
The second is how to correct: rebuild, replace, tune what I have?

Look on the airhorn of the choke in the drivers side, front. There should be a number stamped on it. It might say "List XXXX". Hope this helps.

Good news is that 2v carbs are pretty much "dime a dozen" it seems.

sounds like a vacuum leak to me.
