Hmmm, why would you want a 3 speed manual behind a v8? This is one of those cases where "Manuals are more fun to drive" really wouldn't apply. I admit, I haven't driven a v8 with an m15, in fact I don't think I've ever seen one. Most of my experiences driving 6's equipped with an m15 have been less than impressive though. They get you there, but that's about it. If column shift is required just go an auto.
