I don't think you would get anywhere close to that. I think the standard for the racing boys is 444cc and for road use 428cc. Maybe it would be better to buy a 600cc bike? Or if your really handy stick a CBR900 engine in, it can be done.

I would imagine that its completely unfeasible or incredibly expensive. If you really want a 600cc engined cbr400, put an early cbr600 motor into an nc23. Its a fairly easy transplant.

The biggest I know of is 480cc unless you replace the engine.

like others have said - it's just not possible
you will be boring from 55mm to 67mm, so liner would need changing and the cylinder walls will probably be too close

Well, it's easier than taking an nc29 motor out to 600cc!
