Re: 4L80E Transmission (86VETTEMAN)
There are a few of us that have done it, not that big of a deal, just a lot of work. I had to have a new custom extension housing , and driveshaft made. I used a Speed Pro controller, I beleive they a called FAST now. It worked really, really well. I will do it again when this 700R4 burns down. One of the others I have seen was done with a welded bracket, looked pretty slick. I think you could do a search and maybe find it.

Bob86zz4 installed a TH400 with GV overdrive, almost the same thing.
You would probably need to make a modification to the bellhousing, then fabricate a torque arm and driveshaft. It will be stronger than a 700r4.
Try running a search.
