Yes there is a large square oring that is captured under the hat.

I had to take the o-ring and trash it. I got a quadrajet air cleaner gasket, and used black permatex on both sides to get it to seal.
I always wished I had a smoke machine to help look for my boost leaks.

Answer his question when you get a chance Mike.I know your busy right now but this is very important.
I have all new receipts on the t-bird showing complete new front end components.Balljoints/tie rods etc.I can tell she hasn't been lined up after the work because she's all over the road when I give her the juice and hit 70+ she gets dangerously squirrely.The feeling of improper alignment feels different than a loose steering box too.I don't know how to describe that though.Rather than just slop and slow to respond steering,more "floaty" if you will.Worse than a loose box by far.Hard to handle.Near impossible to keep her straight,unlike a sloppy box.

Like someone posted above, make a boost leak detector and then use soapy water to check all of the connections.

I like the boost leak tester idea. But with a v8 wouldn't a valve be open at almost any crank position? Therefore holding no pressure?

Excellent question!
The simple answer is Yes, a valve would be open, but in order for the pressure to escape, two valves must be open on the same cylinder. This only happens on the overlap period when both intake and exhaust valves are open.
The stock IDI cam has 38* of overlap. Multiplied by 8 cylinders = 304* of overlap.
Since the IDI is a 4 cycle engine, it takes 2 crank revolutions or 720* for this to happen.
720 - 304 = 416. So there are more non-overlap degrees (416) than overlap degrees (304).
You just have to rotate the crankshaft to a non-overlap position. That's the theory.
In practice, when you apply pressure to the intake manifold it will force the piston with the open intake valve down. This will be counteracted by the cylinder undergoing compression.
The engine should quickly find its equilibrium.
Worst case you might have to manually rotate the engine to a non-overlap position.

Hey laserjock I know you ordered a new fan did you get it, did it work?
I'm waiting in a new ford fan too but I might just try the oil trick in the meantime to see if it works and also in case the new one doesn't show up before my camping trip.
I'm hoping you get dialed in before your trip good luck![emoji1303]

Fan clutch is coming tomorrow.
I put the Redhead box back in. It behaves pretty much the same. But I can hold it straight going down the road now.
I took a video of the engine sound. I posted another thread. Take a listen and tell me what you hear.

i am just starting to wonder if something else is amiss with your steering. is your steering a tilt column? i know they have a small universal joint in the column itself. you could also have some slop in the shaft in the engine compartment where it can collapse on itself. loose drag link joint? track bar? i wish i could put my hands on it to feel where the steering slop is. it just seems a little at odds that your two steering boxes would act the same.
maybe it is my speakers but the engine sounds normal to me.

There is a small amount of slop in the shaft but most of it was in the box. 10:1 the valving is messed up in the box. I'll run it a few days and see if it improves. I'm guessing it won't. Slop I think is acceptable now.

BOOST!
Mike, do you mean the red head is behaving the same as it did before? ( issue turning one direction ), or the same as your other box?

So many wrenches, so little time...
Mine had a very tight spot- presumably where the pitman arm is centered-
Is the pitman arm centered with the drag link? Or off to one side
Or is it harder to turn the entire time to the left
