Slant revival

I recently aquired a 62 Dodge D-100 pickup with a 225 slant in it. I'm going to try to restore the truck in the near future, but want to get the engine running before I start with the body. The engine is in nice shape and I just rebuilt the old 1920 carb. I'm assuming a new ignition system is preferred? Ultimately, I just want reliability and whatever mileage I can get out of the engine. What would y'all say would be the most reliable and economical combination for the old truck? I don't want to rebuild the engine yet, either. I'm on a budget at the moment. Thanks, Forrest.
