Yet the LS3 has run 11.7 showroom stock.
Now the coupe is about 3300 lbs which makes it 7.67 lbs per HP
The CTS V is 4300 lbs which makes it 7.73 lbs per HP
Basically identical from that aspect. Yet it shouldn't be almost 8 tenths slower. Compare what you will, these engines don't have that much not in common. There are may similarities between the LSX engines

If 100 pounds equals roughly .1 seconds in the quarter, then that half ton deficit should put the CTS-V around one second slower than the LS3 Vette. Now we're talking about a 12.7 quarter. Now add in the 120 hp benefit to the Cadillac. Now factor weight distribution, less agressive gearing, smaller tires, more aero drag, less efficient, etc. You seem to be underestimating the effect weight alone has on the entire equation, much less everything else. Will it run faster? Probably, but not by all that much.
