My dad's '10 Charger R/T Hemi AWD w/Road&Track Package works pretty good. You can get a good 4 feet of rear wheel rubber laid down before the front wheels kick in. Ask me how I know
Back on topic: There should be a lot of ways to get a manual behind a LSx with an AWD transfer case but it's going to shift like a truck, because thats where the manual transmission will come from.
