Offenhauser Dual-Port manifold

[73CS]

Has anyone used or heard of the benefits or drawbacks of the Offenhauser Dual-Port manifolds. Where the primaries went down one port and secondary down another? If they were good why don’t they make them anymore? Thanks

I have an Offenhauser 360. What is the story on this intake also? How does it compare to a performer?

From what I've heard there better than stock maybe with a tenth, but there pretty old tech. Could be cool for a retro build

I would agree with 1968olds98, old tech looks cool but theres better stuff our there now and if you think about it those split runners are taking up space which = less volume.
