That really depends on who you talk to. There are lots of guys running around on big bore LS1's that make some impressive numbers at the wheels. If you were going to bore one out you would want to use the LS6 block to do it. From what I have heard and read they are supposed to be a stronger block than the LS1 not to mention it also has a better PCV system on it.
People are saying you can take them out to 46x ci and still be fairly stable. But I personally wouldnt go that big. The 427 LS1/6 motors seem to hold together pretty well, make HUGE hp and very streetable.
