A factory replacement "CR8H" is supposed to stall between 1900 and 2400 rpm according to the transtar catalog. I don't know the pricing, but I'd expect around $100?

If you need a higher stall then might have to go aftermarket or ask Transtar above. I got a heavy duty version (better sprag, I think roller?) of a factory high stall 727 converter and it was less than $200.
