Dont know which way to go

Ok,since Ive aquired my 72 Duster,Im undecided as to how to fix it up.
Part of me wants to turn it back to original or a minor restore(Paint it the same factory color,rebuild the slant 6,etc)Part of me also wants to do a complete restore(full on restore)as in take it completely apart and restore it completely and I also want to do it up complete street machine with a v8 swap.But I look at the cost of a all of this and the work also to convert to V8.I'm also finding the parts where Im at(Colorado) nearly hard to find.Maybe a little advice maybe?Well,whichever direction I go,Ill keep everyone posted.I was also thinking of just finding a Duster with a v8 already in it,but no luck in that around here(theres ebay,but I dont want to pay 4000 for a overpriced basketcase)
