i think it's a 500 something but i'm not 100% on that i think there should be like a info page on this i think it's the most asked question for a 400ex ever

Ya there is a 500 kit. It's bored and stroked to the absolute max. going to be big bucks to do it right though but I've heard that they are unbelivable. The 460 is probably the best bet if you want to keep a little reliabilty.

on just bore you can go up to a 465, but stroked i have seen up to a 510.
