Been a few years since I delt with this, while my race car was still a street car. Seems like it required an input shaft without the passage through it, or the hole in the shaft plugged. Wish I could remember which. The people at TCI or ATI could tell you.

That 3.06 low gear is not likely a big issue for your car. Mine was like a tractor. Standing straight up, or spinning the tires. Front end stayed up through second gear in good air, if it hooked well. Likely not so much of an issue in a 4000 lb car with less hp. Big RPM drop at the shifts won't help anything. T350 trans was faster.
