340 -727 -3000 stall- Vibration under load - Trying to find source

I'm shocked at how many people don't know that the converter change wouldn't fix the problem. It's not balance related. Don't take my word for it; google "centrifugal imbalance"..or something related to that...I don't have time to find more sources for the obvious.

So you're telling me that an improperly balanced converter would not have an effect by changing the converter out? Where do you come up with this stuff?
One of the reasons for changing the converter was that he did not like the RPM that it engaged at.
I think he has a cast crank balance job with a neutral balancer or something strange like that.
