400ex question
If the only thing done to the engine (ignoring the bolt on mods like filter, and pipe) in the 440EX, I'd say the Z400, mainly because from personal experience, I have a friend with a 440EX, with just the big bore kit, and my other friend with less riding exp beat him on top.

I would assume that anyone that puts in a 440 kit would put in a new cam... Otherwise they're better off not doing anything at all if they're into drag racing. I've personally seen 440EX's where the owner just slapped in a 440 kit without taking all the other variables into consideration, and then they wonder why stock bikes are winning them in drag races.

Also take sprocket size into account. The 440 will definitely put out more horsepower, especially if it has a stage 2 to breathe better, but this power will be useless unless the bike is geared right. I would say that the 440 would be able to take the Z400 fairly easily if both riders have nearly the same riding skill.
