I don't have an LS, but an 'ol run of the mill Vortec 350/4L60 with 210k on it. I have 295/45/18 which is about the same size as urs, mine has 3.42s in it. IMO, it's a good happy medium. Acceleration is OK, but then I can do 100 without the tach bouncin' off the rev limiter. Would go more, but need to tune out the speed limiter. It keeps pulling till it hits 100.
