Hot Rods Need help on manifold ID

Has anyone seen a manifold like this. We can't see any manufacturer name on it. It has 3 48mm IDAs on it.

 

Offenhauser.

 

Offy still makes those... At over 400 bucks a pop....

 

Offy may have made that for some private reseller who wanted the name left off.

 

Perfect thank you all that helps. The intake has been polished, someone may have ground off the lettering.
Isn't there a name for this type of manifold?

 

Resembles the old Smoke ram with the interchangeable top. Could be had as single 4 bbl or cross ram.

 

graybeard my thought exactly, looks like the 69 Z-28 cross ram with a different top instead of the dual Hollys.

Pat

 

Offy calles it their low profile ram. They have several tops to go on that same base. Scroll down to page 26. Offenhauser catalog.pdf (exeterautosupply.com)

 

I’ve never seen any 2x4 top for a SY-1 Smokey Ram, the only reason the top could be removed was because there was no other way to access some of the intake bolts. Naturally if someone wanted to modify the inside of the manifold that would be a plus.
The manifold @Richard pictured is an Offenhauser Crossram, it is practically a direct rip-off of the Chevrolet over the counter crossram designed for the Trans-Am series run in the late ‘60’s- early ‘70’s.
Offy had the 2x4 like GM, the three Weber top shown here and there might have been a single 4 bbl. top too.

 

So, are you thinking it's not offenhauser? It looks alot like the cross ram setup in the Offy catalog.

 

I have gotten Offy parts, from Offy, in their packaging, with no logo on them.

I have no way to explain this.

 

No, I did not say that it’s not an Offy manifold but I did say it does have many similarities with the GM manifold. They appear identical but a direct comparison with them next to each other might say otherwise.
