8 3/4 vs Dana 60

OBTW, this is is not about egos, it is about getting the facts straight before you start giving people advice. So which is it, the RP400 or the MO400 you are talking about? I have a pet peeve about people talking BS when they are giving advice about stuff they know very little about. I'm no expert, but I can spot BS in a heartbeat. Sometimes people have to save up a long time to spend their hard earned dollars based on advice they might read here. Get it right.
