The install is going to be very similar. The trans, flywheel, converter, bolts, etc, are all going to be the same.
The only thing I can see being different is the fabrication of the crossmember and the driveshaft. We've done a few 2wd, regcabs here and we used the same ds, just changed the slip yoke and it went right on.

i dont know about the driveshaft but the 80e will work on a 4.8 but y would u put it behind a 4.8?...that will just rob more power that the 4.8 dosent have

shut it LOL yeah i guess your right well even if i droped a 6.0 in i would still have to worry about the drivsaft well i guess after all that a stock one from a HD would work bu then i would have the rear dif issue good grief i guess ill just trade mine in for a HD and just spend money on that one lol

should change the title to "How to swap a 4l60E to a 4L80E" if you want more hits. google "fastest stock internal 4.8" and let me know the first couple of pages they give you

is there a flywheel spacer for the LQ9?

It didn't come with one but you can put one on it if needed.
