Define "Ideal"?? We used to have a loose 8" that would stall 52-5400 behind the typical junkyard 284-484 440. You know, the kind of motor that was all done at 5800! 400-600 rpm is definitely not ideal, but it sure was fun!! It would usually be a tenth quicker, and 2 mph slower than the common 10" 3600.
If it's strictly a race car, especially a heavy one, how well the converter and torque curve match, may determine a lower shift point rather than raising the stall. 10% above peak torque rpm used to be the rule of thumb for stall setting, but I think modern agressive converters can be a little closer to peak, and deliver the best performance.

Ideal I use 1500 rpm... I dont know if its the best but that works for my set up so I dont spend to much time at the stall point on the shifts

Mines a little low right now with the W-9 but worked fine with the W-2... its 5600 stall and I shift at 7800 and hit the traps at 8100-8200 on the W-9

That's what I've been told repeatedly from many sources. But I am not doing it since my truck is street driven.
Using a 3800 stall in my truck and a 6200 rpm shift point. I doubt it will really suffer any. Or should I say I wont be missing anything.
