Tourqe Converter
It should feel pretty tight for a d/d. I had a TCI 3500 stall with a 2.5 str with my 3.23 gears and I loved it. Recently switched to a Fuddle 3400 stall 2.2 str, but I haven't driven it yet. Talk to John at Fuddle and he'll hook you up. He's a great guy and is willing to spend a lot of time on the phone to make sure you get what you want.

get a lockup stall converter, as it will "lock-up" like your stock one and the other will not lockup...and will be slipping constantly.
i'd look for 1.6-1.7 60' and low 13s/high 12s in the 1/4.
