intake manifold fittings and where to buy them - 340 small block

[plymouthman72]

Hi all,

I am putting the last pieces of my 340 together and noticed I do not have all my intake fittings for my rpm air gap. I tried searching online and am not coming up with much. Maybe because I am not wording it right in the search? There are 4 ports on it and I think I have 2 figured out but not sure about the other 2 (noted by the red circle). The one on back is for the power booster and the front right is for the heater core hose but I have no idea on the other 2. Does anyone have any experience with these? I think the other large one in the front may be extra but that leaves the smaller one. Do I just plug these up?

Also,do you guys know what I can put in to the search engine to pull up the right parts? assuming they are able to found that is.

Thanks so much for yall's help.

Just plug the one not needed by the thermostat housing, as for the fittings, Herbs has them here:

But since originality isn't an issue since you are using the air gap, I would just use brass fittings readily available at any good auto parts store. You can get a wrench on them and will save you a couple of bucks. Really good street intake by the way!

This style is a lot easier to get a grip on versus the style with the "slots" at the top.

I've seen them in several lengths and with the nut shaped portion in various lengths and positions.
