Help...need advice on best ignition system, carb, timing...

You don't need and MSD or Pertronix bullcrap. PM Trailbeast and let him tell you about his new distributors he is offering. They are remanufactured stock Mopar electronic distributors modified with the 4 seconds flat timing limiter plate and light springs. That way you can have initial timing around 20* and a total around 34* depending on how he installs the limiter plate. Stand up guy and you are supporting a forum member, plus his prices are WAY more reasonable than Pertronix OR MSD and they drop right in where stock Mopar distributors go.
