You don't need to have the Bigger flywheel. a mild cam Like a Rv style the stock convertor will be fine. If you get more then that get what the cam would call for like maybe a 2000-3000 stall You realy shouldn't need much more then that for a daily driver No how. As for the 3:55s I wouldn't go any more then that for the street Unless you plan on running a taller tire Personaly I'd go with a little lowwer gearing to like a 3:32 But seeing that You already have those try it and see out it works out for you. You can always play with the tire size rather then buying a new set of gears.
God doesn't like ugly.
