VERY TRUE! Let me expand on that, and go a bit beyond the carb. On *major*
part of "setting up" a carb is making sure the air/fuel mixture has a clean,
easy path to every cylinder. The theories and practices of making a good
intake manifold would fill a book (or two). But the one golden rule is NEVER
have an uphill run. The weber manifolds for the Spit/Midget 1500 are uphill
for their entire run. These things are terrible. The adapters used on
the TR6 are worse. They have one run that is straight up.
Having had the unfortunate job of trying to tame five of these conversions
(3 TR6, a Z-car, and a M-Bz), I can comment on the performance. It's bad.
Cold natured as hell, fuel hungry, and, due to the fuel puddling, very
prone to flooding during cornering.

Holley makes a virtual clone of the Weber DGV. This may in fact be that carb.
I've heard that Holley rated their 2 barrels at a 3" depression rather than
the more universally used 1.5". A stock DGV I've been told is at 225 cfm.
Flow rate gain is not linear with depression increase.
As a point of reference, Vizard lists (at 1.5") the flow of an SU HS6 at
210cfm and a HIF6 and 240cfm. I would imagine the CD175 is in this range.
