ever such thing as a hi po 2 barrel?

I have a 2 barrely intake off of a 70's model 318 that is higher up than others and also has a edelbrock design sort of a x for the tunners but it is wide open on the inside maybe this was a marine intake? I know it hauled but in the valiant it was in. I am sure its not "high performance" but I know its a lot better than others. Anyone ever heard or seen this intake I might get a picture.
