Congrats on the SS, I always liked those cars, especially being an LT1 guy myself.

As far as the converter in your car goes, I would guess that it probably uses the same converter as my Formula, which has a stall speed of 1800 rpm. Mine does feel a little bit loose sometimes at low speeds, like in parking lots for example. Obviously this is done for performance reasons.

Does this car have a solid axle or IRS? I'm wondering if it uses the same 10 bolt rear end as the F Bodies. If it does you should be able to get some 2.73 gears from an F Body, that would help. But I think the biggest gain would be swapping to a T-56. As waffle said the only way to load this engine effectively is to get the RPMs very low, and the 4L60E just isn't going to let you do that. This is even more true of your car, since the iron head B Body LT1s use a different cam than the F/Y Body LT1s which is geared more towards low end torque.
