The second pic shows the edlebrock 3864 I have, and it doesn't has a vac port. In the first pic you can see that there is normally a vac port on the TB that connects to the pass valve cover.

But my tb has no vac port, so what should i do about the vac line for the valve cover?

 

i've found that atleast one of your ran vaccuum line to from the pass port to a nipple on the CAI.
