What stall speed would you pick?

I'm using a built 200-4R for my otherwise-stock build so that I have overdrive; I also have 4.88s in the rear, which become 3.08s in overdrive.

I made the bad choice of leaving a performance converter, maybe 2800 stall, from the last car I used the trans in. Since the trans comes from an '87 Grand National, I had two options for stock replacements:

a) The 3.8L Turbo converter, 9", 2000rpm stall
b) The 5.0L V8 converter, 10", 1400 stall

I went with option B, but the shop has spooked me a little saying it might want to push through intersections. My cam is quite mild, almost stock (214/218 @ 50), and I'm hoping it will idle at 600 or so in drive.

I guess it's a little late now, but which do you think would be closest to the stock TH400 converter stall speed?

Thanks
Dave
