i have a 400ex with 440 kit. needs to be bored . does any one make a over size piston for a 440 kit?

Don't believe they do. That's one of the downfalls of a 440, once you do it and it needs re-built you have 3 choices. Get a stock sleeve and start back at square one, get a stock sleeve and bore it back to a 440, or go big and put a stroker kit in it.
