most double pumpers are dual feed......that means it has 2 fuel inlets..I know you have seen those chrome lines that go to the front and back bowls on the carbs.........that is dual feed........a quadrajet would be a single feed.......just has the one fuel inlet.........the Holley 6210 and a few other quad replacements are double pumpers, but have a single inlet, for ease of use and fit.........as for size.800 should be fine.........mine is a 750 and I have pretty much the same thing as you, except Merlin heads on mine ....hope this helps

As far as intakes....spread bore is the pattern for carbs, such as a quad..small primaries and large secondaries...........all you need is a square bore for a Dbl. pumper holley..........the oval/square port thing, depends on what heads you have.............
