It's a 3.23 Saf-T-Track (assuming it hasn't been changed).
I took the TH400 to my trans guy and had him dyno test it before I put it in. While I was there I had him build me the biggest, tightest torque converter he could muster. I think that the change from Slim Jim to TH400 is going to make such a huge difference that the converter will not be that critical (especially since my Slim Jim was in such bad shape).
Besides, this one is my "low & slow" cruiser....for toolin' around with the FM radio blaring and the A/C on...:D
