1965 273 4-bbl intake. What is this connector for?

[RustyRatRod]

That casting goes ALL the way through the intake. I wonder if they put it there for an optional PCV or crankcase breather?

I saw that so that makes me wonder....WTF? lol

Yep, me too. I have never seen anything hooked to it and never explained what it is for.

Just a bulb shape on the bottom side. It doesn't feed into the runners. In 66 the CAP (first year) was a hose from the air cleaner to a vented oil cap.

Dang, all the photos of my engine I only have a couple of my intake and none of the underside. I wonder if I can get upstairs in my garage. I think I have a extra intake up there. I think it's a 66 non-CAP.

It plugs into Karl's butt and gives you the level of his farts.

That's the O2 sensor for my farts... It monitors whether I'm running rich or lean...

What CAP control valve did they use?

That spring loaded gizmo with green plastic cap.

 

[Cuda Al]

On a California car (Barracuda) in 67 it had a port going to the CAP valve and a port going to the vacuum gauge. If you had power braked it would have come out the top.

That's the port in the intake runner.

I thought that was what the OP was asking about...

 

[Richard Sweet]

You could connect a couple wires to it and try any gauges you have. Maybe you could monitor intake air temperature or vacuum. (smiley face)

Mine is multi function, brake boost & heater/AC control. Originally it was just heater/AC control till I added power brakes.

I cannot figure out what this two prong connector is for. Nothing is connected to it right now. It is on an original 4-bbl intake manifold in the back on the driver’s side.

This is in a 65 Dart hi-po 4-speed, manual steering no AC car with an aftermarket 4 bbl.

mine just has a plug in it.

 

[Martin Koiryohann]

What was the original use for the vacuum? I’d guess a power steering unit given it’s location but this car never had power steering. What sized bolt is that plug Mike? 3/4”?

r u sure its the oem intake for the 273 & its not from a lator 340 or 360?

Why the red X on the first post?

The casting number begins with 24 which is a 1965 number

It is the original intake with correct casting #. A later intake will not work on a 65 without modification. The mounting bolts are different angles.

 

[Bret Tschacher]

Yep, someone just plugged the hole.

I had one of these intakes back in the early 80's I installed on my old 18er, I cut the cross out of the center and opened up the chamber then put a 1 in, spacer under the AVS I had on it. Man that made everything wake up. Those old intakes like to have more room under there.

Right there. They are pretty flat. Not much plenum or rise.
