Carb Vacuum line routing and elimination - Keeping charcoal canister
Hey guys looking for some suggestions on the extra vacuum lines under the hood of the 85 I am working on dropping a rebuilt 350 into. Going to have a non computer carb and intake does not have egr.
This is a diagram I found here on the site, I marked out what I should be able to get rid off since there will be no computer sensors or egr. I am keeping the canister and pcv.
what lines that are not already marked out (if any) are extra or redundant that I can remove or condense down to help clean up the engine bay more?

I'm in a similar situation and would love to know the best way to go about this also. All I have is the canister, though. Someone already yanked everything else out before I got to it, but I'd like to add a PCV valve and hook the canister back up if possible.

Can #B just be hooked up to any filtered fresh air source?
Rather, can this be made to work with an aftermarket carb that just has manifold, timed, and PCV vacuum ports? Frankly I'm not really familiar with the intricacies of vacuum systems.

I'm sure it can. The quadrajet has a lot of vacuum connections, all at different heights in relation to the throttle plate. But for the most part, they all come down to either Manifold, Timed, and PCV vacuum, as you said. So it is doable.
Looking at the diagram, "B" has to connect to Manifold vacuum. I can look at my quadrajet to verify.
We have a member here who I consider to be a quadrajet "expert". I hope he sees this post and chimes in.
