Where to start looking....

Sorry guys, I forgot to mention that the car also has a MP electronic conversion kit installed on it as well.
@ Bad Sport, I've got a regular (10A) charger on the battery now, w/o the battery cables. We'll see what ensues when I get it fully charged. I think you are correct, in part, about a drain somewhere. Maybe a combo of a bad Battery Tender, and a draw somewhere on the car. I will post results on that later.
@ Cosgig, I am definitely going to start going through the electrical system. Been long overdue, most likely, living on borrowed time! I already have a brand new enging bay forward harness, was going to install that when I drop my 340 in. Thanks for the suggestions Geoff. As soon as I can figure out the electrical demon causing the dead battery issue, I will do those items listed above.
