I'm doing a 1974 BBD conversion to replace my Holley 1920. So far so good! What are people doing to plug the extra three BBD vacuum ports? And is there is a preferred port for the distributor vacuum advance?

Distributor vacuum is on the Pass. side (Edit: I shouldn't have said passenger side, considering it's on a slant 6- I'm used to V8s... I should have said "the opposite side from the throttle lever"), PCV is on the rear base, cap the rest. Bowl vent should be left open unless you have a fitting for it on your air cleaner.

Nice graphic. thanks! I couldn't find that info in the online BBD manuals. I wanted a 70's model air cleaner but they are stupid money on FeeBay. I ended up with a 60's air cleaner with nothing but a snorkel attached. What is the clean method for capping? Hose and a rod inserted?
I didn't find that opinion on BBDs when I was researching the conversion. That and finding an unmolested NOS was appealing to me.
I bought a heap of caps and plugs on Amazon, like these. I don't think I got this exact one, but you get the idea. I use them all the time.

You can also get them at most any auto parts stores, and most hardware stores.

Thanks! I ordered ten bucks (a lifetime's) worth on Amazon.
