I have two of these. One has had the plug wire holder thingies removed.

What are they ?

And what kind of breathers do I need ?

I would like an oil fill and a PCV attachment of some type, but if it's not meant to be, then I won't use them.

I am going to guess that they are 1964 vintage and possibly c-body. You can still get the parts.pcv

iagree Pretty sure '65 and up C body only had ONE big spark plug wire bracket on the passenger side rear only. If not '65, '67 to '68, plug wire routing and brackets changed in '69. No C bodies in '64.

I've changed my mind, now I think they're late '50's to '63.

Hmmm, I thought the 6-bolt deal started in '64.

The tubes are ~~ 1.400" diameter.

That's right, I missed the 6 bolt detail. So 1964 big car I guess?

I had a set of those valve covers on an '70 pickup truck. I assumed they were original but perhaps not. They worked good with the truck exhaust manifolds.

They are definitely sweptline era truck. I have a set that came off of a '68 W200 with a 383 2-barrel.

On one side is the breather / PCV line, on the other side is the oil fill ?

The breather slips off for an oil fill. They didn't add the oil fill cap until after the breather stands went away.

Ok no c-bodys. So how about 1964 chrysler with a 361 or a 383???.
