Question about stall converters.

Up until now, the stall converter was one of the most effective mods anyone with an auto could do. One of my first mods to my lt1 was a converter...the ls1 guys sweared by them. Why are folks not trying them as a simple bolt-on mod for the ZL1s? Is it the warrantee?

I would imagine that a converter alone in one of these cars has got to be good for at least .4 in the quarter. Though I was able to get a 1.74 60' on street tires on my 11.9 pass, I'm sure that with a good converter and a set of drag tires, I could run an 11.4 with nothing else done.
