I bought a 200 six and three speed tranny, still in a Maverick, from a guy on Craigslist. The guy had a cherry picker, but didn't have time for the next month to pull it. I said I'd pull it if he knocked $200. Ha said he had an appointment that morning and couldn't do it right then. I told him to go get ready for your appointment, and I'd have it out and loaded in less than an hour. I made it right on time.
Sixes are great!
Since you'll have the pan off, I'd pull a couple rod and bearing caps for a look.
If you don't know the history, plan to replace the timing chain.
I'd replace the freeze plugs while it's out.
I won't have it out in an hour but I don't think it will take me too long. Lots of room in comparison.
I do love this six; it runs like a top. What I know about the vehicle is that it has 108k on an engine that hasn't been rebuilt. I plan to take a close look at the things I can while it's apart. I was also thinking about the timing chain, but hadn't considered the freeze plugs. Seems simple enough.
