Does anyone have experience with this offenhauser 2x4 intake ?

I have the same intake #5488 without the crossram. Its mounted on our 67 273. Heres a thread I started on it.
The carb linkage and throttle cable will be the hardest/priciest. I made my own linkage.

I just bought it this weekend at mopars in the park. Any experience with it good/bad or is it just a wall hanger.. Bottom # is 5488 and the runners are #5497
