I personally prefer a higher than "stock" stall. Your torque converter actual stall is a factor of rated stall and torque applied. It will change based upon the amount of power applied. Obviously gearing affects this, but it is not a true linear amount, so 2:1 gearing downstream does not affect stall by 2:1. As said before, the higher the stall, the higher temps encountered in the tranny. Mine is somewhere between 2200-2800, for actual lockup, and I had the converter modified to lower the stall last time through the tranny, as there is not hardly anything available for my setup and I was seeing a lot of heat. Stall is not the point that the tranny starts to pull, but the point that the converter won't "slip" anymore. The higher stall tends to allow more control to ease over obstacles for me. I have driven both low stall and high stall rigs. I would recommend something higher than stock, but probably only 600-1000 rpm. Anything more in a trail rig just generates too much heat, in my opinion.
