Intake manifold questions

The street dominator is what I run on my 340, in my van. The main reason I bought it back in the 70's is for the clearance in the dog house.
If you want a really good old school intake, find a Street Dominator. Also a single plane, but they lose nothing on the bottom end. They have a full, open plenum and not the funnel crap of the Streetmaster. Still available reasonably.
