I figured the latter was correct since the car is an auto with a sunroof. I think the manuals come in around 4100 lbs.

my car is exactly like yours auto/sunroof and it weighs right at 4400 race weight. Do drag radials, pulley, tune, air intake first before you stuff a looser torque converter in your car. Normally aspirated cammed cars...definitely need a looser converter but the ZL1 has tons of low end torque. You will find it difficult enough to hook with the stock converter without shocking the car even more with a looser converter. IMHO.
