I have a T86 OD in my 2R11 and it works well, but just has the 245 motor and I don't drive it aggressively enough to worry about breaking it.
But on the other hand, my 2R15 project has a NV4500 sitting in place waiting patiently to be finished at some point. But that is because the original, ridiculously small for the truck Champ motor got tossed and a 392 hemi is taking its place. Figured I needed something a bit more stout for that.
If the T86 came with the 289 and you aren't planning to stress test it too much, I'd probably just leave well enough alone and keep them together.
