Anyone ever run a Offy dual port on a 390? How did it work?

They were good in the Old days but when I tried it I was not looking for street power I was building wheel standing tire frying motors. I drove with it on for a week and then my dual 4v manifold showed up. I could tell the street difference in the drivability. Because of the restriction the manifold was not good above 5200.
