Also check the RPM of the engine while it is in drive, check the dwell on the points. Two very simple things ,and both could give you the same problem.

A vacuum leak will cause this problem also make sure your chock is opened.

Hello my name is Chris. I have a 1973 dodge d100 with a 318 and I had this same problem a few months ago..... If yours is doing what mine was doing it will idle fine but when you put it in gear it wants to "bog down" and if you press the gas at all it dies...... my truck was out of time so I reset the timing and that stopped it. Try resetting the timing and see if that works. I hope this helps. Please let me know if it works. If it doesnt you might have to get the carbuerator rebuilt.
