4" safely.
4.100"/4.125" with a excellent builder who knows what needs to be done to the pistons to make them last.
4.185"/4.250" is almost unrealistic, but it has been done. I don't imagine th erings would last long at all, and it would probably drink oil like a 70's ford.

so realistically a 400+ ci engine on a stock block is kinda dangerous then? really want to run a 402 or 408 on my stock block so i can keep matchin #'s. 402 is the most possible at 3.910/4.185. btw my car is 2000 so i dont think i have the ls6 block

you could gut you an l92 bottom end that starts life with around a 4.06x bore and throw in a 4.1" stroke for 426-427 cubes.
check with the vendors on here,they should be able to steer you in the right direction.
