Default Maximum Bore on the LS2?

Just curious what the maximum bore is on the LS2. Is it just a 350 borred to 366? If not, what can it go to?

Well, there hasn't a 350 in the line up for 7 model years now(the complete C5 line went to the LS1 or 346ci). The LS2 is a 6.0L all aluminum block heavily based on the LSx design with some new oil passages for the upcoming DoD in trucks. The LS1 and LS6 blocks did allow for a service clean up on the bores, but it was minimal and wouldn't be cost effective if you are trying to increase displacement for power.

The bore can go pretty wide with wet or Dry sleeves, almost 4.155+
