Default Increasing gear ratio w/stall = lower revs?

Would your revs drop during normal part throttle driving (before lockup) if you changed from say a 3.23 to a 3.73 ratio? I have a Yank SS3600. I could see the rear gear doing more work to move the car requiring less from the engine/converter. In turn you would see an increase in highway revs (locked converter), lowering your highway mileage.

Or is my thinking flawed?

Yes with a numerically higher rear gear, the engine will turn more revs.
Mostly noticable at highway cruising speeds.

Thanks, but that wasn't the question

It won't lower the revs, that's for sure, not in any kind of driving.
Just did a gear swap myself (2.73 to 3.42), always revs higher now.

I went from the factory gears in a 2000 WS6 to 3.73 when i got my 12 bolt. The biggest difference I saw was at highway speeds at 80 i was almost at 3 grand. The stall pretty much seem the same. People say that it will tighten the stall but I did not see a difference. I have the ST 3500.

That is what I am talking about. With a high stall converter, I would think that with the rear gear doing more of the work your converter wouldn't have to and maybe slip less to get the car moving at the same rate thus turning a little less RPM. But maybe not.
