The maximum bore is 3.910 inches, which is the same max listed for LS1s and LS6s.

Correct, we've had next to no problems boring them out to the 3.90x to use the LS1/LS6 pistons. of course it is always a good idea to have the block checked out by the machine shop prior to boring to ensure you're good to go.
