What color is the smoke? My 98 Smokes on WOT downshifts to high RPM's but I've seen low mileage LS1's do it so i guess it's not uncommon.

to be honest i have not seen ls1's that do not do this on the upshift......i would not worry bout it probly just from being loaded up on fuel right at the shift...
