Is there any interest in a parts list/writeup for swapping a 4L80E into an LT car? When I was doing mine I found a few threads from guys with an Impala SS doing this, but there was practically no documentation for F-Body cars. It doesn't seem to be a very popular swap so I'm not sure how useful it would be

 

You might have better luck on thirdgen.org, because there are plenty of guys who have swapped LT engines into third-gens.
I've never really looked into it myself, but now you've made me curious about what would be necessary.
