Torque converter stall speed

I’m building a 512 stroker for my 73 challenger, it will have apx 550 hp. The 440 I have in it now is 350 hp.
With 3.55 rear end and a gear vendors over drive I’m running 2200 rpm at 70.
What stall speed converter should I use? A Hughes HUG SEH2832BL-10 flat tappet cam
I have power brakes and a/c
