Since it does not sound like you are wanting anything particularly original, then I second the thought of doing an HEI conversion. The extra spark energy really makes a valuable performance difference. I do believe Trailbeast sells HEI conversions for the Mopar distributors.
(And I don't have any bias to any particular one... I raced 4 bangers for ages on points to 8+K RPM. Totally reliable and easy to work with once you learned them.)
