Default 1999 vortec 454 missing!

Help would be much appreciated!!!! I have a miss at a steady cruise. Idle seams to be fine. When i rev it up to 2300rpm or so i feel a miss. i already did a tune up. I have checked on line for this problem. Seems that i could have a bad dist. gear. I also have heard that it could be a bad cam lob/lifter. Any help is much appreciated!
