Has anyone decided to do this yet? I do a fair amount of interstate travel as well and I think the 3.15 would definitely improve fuel economy at 70+mph.
Performance around town worries me. It seems like the transmission doesn't kickdown as quick as I would like so even now and the car feels like a dog sometimes. It would be a lot of work to do the swap and have to revert back.
