Default TH 400 Transmission Stock Stall/Lockup Speed

Does anybody know what the torque converter stall/lockup speed was on a stock TH 400 transmission? I've been told varying stall stall speeds from 1200-1800 rpm . My car came with factory AC so I believe the rear end ratio in my car is 3.23. I've also heard the peak torque rpm on a Pontiac 400 is around 2300 rpm so the best torque converter for this would be one that is around 2000-2400 rpm? Of course it may not do much good getting an aftermarket 2000-2400 rpm stall speed torque converter unless you have a limited slip or positraction rear end.
