? on torque converters

OK, which converter should I use from Mopar Performance? The 145K = 1900-2100 stall, the 166K - 2250-2350 stall, or the 175 = 2400-2500 stall.
I have 3.73 gears in an 8.75 sure Grip. 24.75" dia BFG's. A 727 with a TF-2 shift kit in a 73 Dart roughly 3200-3300 lbs. I don't know how much hp my 360 will put out yet. Oh, I won't be dragging this car it's just for on the street and some highway.

OR...does anyone know what the stock stall for a 360 is?
