I haven't ran the part number on the sticker on the torque converter to check the stall, but I'm expecting it to be a truck 1,800 stall. Unfortunately my 200-4r converter won't work on the 4L60e, which has a 2,500 stall converter. After I drive the car for a bit with the turbo I plan on diving deep into the 4L60e and fully rebuild it, with some good parts, and at that time I'll get a decent torque converter for it with a much higher stall. In the mean time, I have a set of 4.56 gears I may be installing in the rear.
