Is it possible and if so what all would need to be done for it to work? Also is it even a good idea?

 

2wd or 4?

 

It's for the truck in my avatar

 

that tells us nothing...

 

Yes. A bit. Maybe.

 

Not worth it.

Do 4l80e instead or 6l90 if you want the 6 speed.

 

Doesn't show it on my cell sorry .... cherolade has a real nice 2 wd (built) for sale and I have a 4 ad stock one 90e, that is

 

2wd lowered 2/4

 

Depends on your goals. I had a guy tell me his buddy's cammed 5.3 and 6L80 was running low 12's, if I recall correctly..all motor.

 

You'd likely need the regular stuff for a transmission swap
The transmission, cross member would have to be modified, likely slid back, probably a shorter drive shaft. if you have hptuners someone maybe able to build a tune for your truck. As far as plugs I have no idea.
