Without going through all the posts and reading everyone else's suggestions, I would suggest a $75 Pertronix conversion for the distributor. If your points are bad or misadjusted, that would be a possibility, but with the electronic ignition conversion so easy, why wouldn't you want that?
My wife came up with a good one. When I did that, she asked me what would we do if there was a nuclear attack? The truck wouldn't run. I looked at her with a blank stare and said if there was a nuclear attack, we wouldn't be around to worry about if the truck runs or not!!!
