I've looked through a ton of threads, I've looked at the specifications page on the home page of CK5, and I'm waiting for my Chilton's to show up. With that said, I'm looking to find out something so stupid and obvious that I feel like an idiot for asking: I have a '74 K5 with a TH350 (I know what the pan looks like through the crud and can ID that). The specs page says that the automatics in '74 were a 205, but the transfer shifter shows all 4WD with no 2WD. With the junk gunked up under this thing (I've never had it running yet so can't tell if it's accurate but from the way the rest of the Blazer looks, it should be) I can't really tell what the transfer looks like. In all honesty, I'm new to working on 4WD so I probably couldn't tell it I could see it. Can anyone give me the quick and dirty on what this might be? 203 or 208 is my guess, but that's all it is...a guess. Thanks for your help with a downright stupid question. Maybe I'm just tired and not thinking straight right now. That would be preferable to be honest.
