Before diving in and swapping out stuff, get to know local mopar guys and hopefully ride in a few BB and SB cars.
There are a lot of little things on these cars that confuse people that come from a different background.
Get to know it before diving in. If you have spent much time here, you may have seen a comment about the seller or previous owner of a car being a 'chevy guy' or 'Camaro guy'. This is not praise, it's shorthand for someone doing something to a Mopar that is not viewed favorably. Try not to be that guy.
