I have a 1-1 throttle linkage 1.250 QFX QuickFuel Dominator mounted sideways on a customers engine for his drag car. It is really easy to change jetting when the weather gets different.

Has to be a good reason why the factories didn't turn them sideways though. Suspect Suspect

I would think ease of operation is the deciding factor. Would it matter which way a carb was mounted especially if each throttle plate was the same diameter, especially on a drag race engine with a single plane intake manifold?

Just askin',

As one of the posters mentioned on a 1-1 linkage set up, and properly tuned no, but if someone just twisted a progressive linkage carb one way or another the slower opening secondaries would cause one bank to run much leaner than the other, even with an open plenum manifold. Dual plane... huge issue

Reason most never did anything like that is the linkage issue. Iniatal carb linkage in vehicles was solid... no steel cables. So linear operation from pedal to throttle made sense.

Race cars have used solid rod linkage as long as they could...

With cable linkage not as big an issue, you simply have a stationary place to mount the cable shell.

Now with dual quads on the ford tunnel ram, I use a cable from pedal to fulcrum, then mechanical linkage to open both carbs.
