Bought a Mopar found some odd issues.

First of all, before I dug deep into the car to figure out what was going on this is what it was doing.

with a new cap, rotor, coil, plugs.
Would run fine at idle, in park you could rev up just fine no hesitation. Put in gear and and put under a load car would pop and spit until around 3,000 rpm then it would take off. Adjusted timing several times same result. tried 2 carbs with same result.

So I took out the distributor to find the pickup coil was making contact. I gapped the pickup coil at .008 And I ordered a new ballast resistor as the one in the car was very burnt looking.
I have not recieved the new ballast resistor to try it out yet. Does this sound like a probable cause for these issues?
any other reccomendations?

Thanks
