I just finished this swap on my '88 351 and am almost done with the write up on it, I also have a few pics of what I did. If you're interested let me know and I'll PM it to anyone who's interested.
I'm very happy with the swap, I did it to get my rpms lower at highway speeds and it worked out very well. With the C6 I was pushing [email protected], now it's [email protected]
The swap is not hard to do, give me a day or two and I'll have the write up done.
I say go for it, like I said before I'm very happy with the swap.

hey injected, sounds like you got a winner. i'm interested!

I should have it done by Saturday evening, I should have time to finish it by then.

why anyone would want to swap out a c-6 for an AOD is beyond me. overdrive is over rated

To each his own, we all do stuff to our rides for our own reasons. I wanted to save the wear and tear on my freshly built engine due to the higher rpms at highway speeds. Mine is a work truck that makes several 5hr plus trips up to the farm.
For mileage I'm not able to say how much of an increase it has been since I'm still working on fine-tuning my warmed over 351 setup. I can say this, I got 10mpg all the time before the swap. The first highway trip after the swap I netted 13.5, that's 3.5mpg and good enough for me to justify the swap. As soon as I get a good tune on the new engine I'll have more consistent numbers on the mileage increase. That's @ 73mph on a 250 mile trip each way, both legs of the trip were made on the same day.
