If you can let us know the plan... Then we can help a little more in pointing you in the right direction.
I don't have any problems with my AOD. When I tow with it, I don't put it into OD.

When I am not useing my 74 van for camping and fly fishing trips I use it for hauling tools and materials for my remodel business up and down steep muddy snow covered driveways. 90% freeway driving.
I did see a 93 351 in a wrecked truck for sale. It has EFI and AOD. Is it easy to make a wire harness for the goodies the EFI system will need?
Is the AOD and 351 the same length as C-4 and 302 or will I have driveline issues?

Am I incorrect in saying the 5.0 guys are taking those blocks to over 400 inches now ?
NOPE, the 5.0 and the 302 are the same block... the 5.0 has provisions for hydraulic roller lifters. bore spacings and deck height are the same.
347 ci is the limit on a 302 or 5.0
The 351W has a taller deck height. 377 & up to 408 ci here.

Most of the guys on the off-road forum recommend the NP205 t-case due to its all gear construction and cast iron case. It was used for F150, 250's and 350's during the 70's and came in both mated and divorced versions. The best bet for a E4OD or AOD connection would probably be a divorced T-Case NP205, I'm pretty certain that they never put a NP205 behind a AOD or E4OD. But I've read that it might be possible to mate one to a AOD as the bolt patterns and spline counts remaind the same over the years. The only bad thing about a NP205 is that the low ratio isn't that low...2:1.
The trucks from the 80's and 90's that had the AOD or the E4OD had the BW1345 (2.75:1) or the BW1356 (2:69:1). I think that some of the early 80s trucks had a NP208 but this was probably prior to the use of the AOD and the E4OD didn't come out until 89. Both of the Borg Warner t-cases are easy to spot because they have large, ribbed aluminum housings and usually come with a tag that states the model number. They both have chain drive. The easiest swap would probably be to find a complete 351W / E4OD / BW1356 from a later model F150 / 250 / 350 or Bronco. I think stock power in 95 for a 5.8 (for example) was 210hp and 330 ft-lbs.
