as long as the top end is bored, or you could buy a stock 300ex top end to put on the bottom end, the mount the same, i am pretty shore.

As far as I know, the jugs are identical,the bore is exactly the same on the 250x and the 300ex, the only difference is the 300 has a longer stroke to give it the extra cc's.
