  The DCOE's are considered "sport" models by the factory, while the DGV's
are considered "production." But there is a whole other line of carbs, best
represented by the IDA, which are considered "race" models.  These usually
have huge throats and no starting circuit, which makes them pretty
ill-suited for road use.
  Randy is right about the DCOE being simultaneous and the DGV being
progressive, but Weber does (did?) make simultaneous downdrafts, designated
as DCS, DGA, and a few other.

  Ok, now its time to give away my secret.  I'm not actually a Weber expert,
I just play one on TV.  Actually, I got home and dug out my fantastic book
on Webers called, strangely enough, "Weber Carburetors" by Pat Braden (ISBN
0895863774).  It's really a good book to get if you're thinking about a
Weber conversion.  It's only $15 and it covers history, theory, rebuilding,
tuning, troubleshooting and conversions all really beautifully.
