Bore an LS1?

Can a LS1/6 be bored, even if .005 or .010? And does anyone make oversize pistons to fit?

OK, so that is .007" over stock. Can I assume that a machine shop would bore .007" over and then hone another .001 or .002?

Cool. I wana put some new pistons in the LS6 and get rid of the slap. It looks like the 3.905 diamonds will be the way to go. I guess if I'm going to go that far might as well put in a 4.00' crank while I have it down.

Thanks guys.
