I have a 1978 plymouth volare with a fresh rebuild /6. I am having problems with it running ruff and idle. Here is what i have i have done 81 block out of pickup 78 head off my motor . aftermarket comp cam. dies in gear very ruff idle new exshate manifold second set of spark plugs valve adjustment checked 3 times will pop back though carb if i rev engine as it is dieing any ideals revs up fine as long as motor is not trying to die

Popping back through the carb sounds like it could be a timing issue.

I vote for TIMING/IGNITION. What type of ignition? Points? Electronic? Vacuum advance?

If it won't idle, tough to check for a vacuum reading...

How about firing order? Firing on all 6? Just trying to eliminate the easy stuff.

Your '78 Volare should have electronic ignition.
I agree with the others who have said that it sounds like a timing/ignition issue.

yes i have checked all vac lines on motor and i have pulled all spark plugs and replaced them with new . also checked tdc on compresson stroke disturbutur is dead on it is electronic but sounds to me to be skipping a beat here and there . will idle in park but after a few min dies out but wont idle at all in gear just dies the only thing i have not done is rebuild the carb which was new 3 years ago but sat for a year while motor was worked over can adjust mixture screws in and will kill motor so dont think carb is clogged tempted to slap a points disturbutur on it and go old school see how that works

well pulling the car out of garage to tinker with the timing some more she died half way out of garage and now is not firing at all fire coming out of coil wire but nothing out of disturbutor so now more problems have spare disturbutor so will try that my next weekend
