The first few posts in that thread are specifically addressing the distributor question. The answer is: there is no reason to spend money on an aftermarket version. The factory distributor is plenty good enough.
Did you click on the link in Post#14? That thread describes the components that are used for a "sixlitre" tuneup, that includes recommendations on a hotter coil too.
I apologize if you felt like I sent you to a dead end. Perhaps all the banter about spark plugs clouded the real information contained in the first few replies.
