Stroking 'cause I'm bored

Now that I have your attention. I personally have searched and searched for the answer to my simple question and to no avail am getting extremely pissed off. So my question is what is the most that you can bore out and stroke a ka24de to? I've read in someplaces 91mm for the bore and 100mm for the stroke, but I personally think that you can push the engine farther than that and still have it be relatively safe,stable, and as a solid race engine. I could be wrong so prove me if I am or show waht you know for everyone to know. I leave you in the grace and favor of the Lord :evillol: .
