tbi to carb with a 340

That distributor will work fine. Easiest wiring for it would be a GM 8-pin HEI module and its external coil. Many posts. Even easier would be a new "ready-to-run" HEI distributor ($45). Many posts on both. If you want to stay Mopar, the 70's electronic ignition, but you requires more wiring and a ballast resistor.
