I intentionally put a tighter converter in my truck when I did the tranny work. It will pull a lot harder because the converter's much more efficient, and you won't have as much "slush" in terms of the fluid coupling beeing too loose. I guess the best way to describe it is that if you're stopped on a steep hill, it will take less engine revs to get the truck rolling-while a looser converter will need more engine revs.
In terms of your question as to whether a super tight converter would stall the truck out-I guess in theory, yes, but the fact is that they don't make converters that have that low of stall speeds-so you wouldn't be able to find one. And if you could find one that would stall the engine, it would be because the engine's fueling at idle wouldn't be able to match the load that the tight converter put on it-hence, the stall. So, it would stall from park to reverse, and park to drive. Essentially, it would be like trying to be at a dead stop with a manual tranny in gear, the engine running, and the clutch engaged-i.e. it'll never happen, as the engine will just stall out.
