Would it be possible......

To have an all wheel drive option for the LS4 Impalla? Would it be able to fit?

I'm unaware how a horizontally mounted engine's AWD system works, maybe a DSM guy can help me with an explanation :help:

The transfer case just comes off a shaft out the side of the tranny on a DSM. The issue is you also need a driveshaft tunnel, and a RWD/suspension setup which I wouldn't think that platform has available.
