    easiest hybrid in a 400ex frame?

    I was wondering what would be the easiest and somewhat cheapest engine to put in my 400ex, it is all widened and set up the way I like it just not nearly enough power. I was wondering whats the easiest engine to get and install with minor mods and still be nice and reliable. I figure a water cooled engine would be alot better than the ex air cooled. easiest engine to find and what years were the best for that one, also about how much am I looking to spend completed? thanks yet again guys!!!

    it should cost around 2000.00 to do right...
