chrysler 3.5 V6 ??

I know nothing about em but think it'd be awesome to swap a 3.5 and an 8 speed into an A-body, if the Chargers can get 31 highway mpg with that combo I'd say an A-body could do better

I guess the one I'm thinkin about is the 3.6? The one that comes in the 2011-? Chargers with the 8 speed...
