I have yet to wire mine to a full 12v, but I have a friend with a 1968 428CJ car that picked up a full 1/2 second in the quarter, by just doing this simple change.

One thing to point out, this is for a Cougar XR7 and they have a factory tachometer. I am not positive or not if the tachometer wiring causes a voltage drop because of the resistance wire or not.

Check if your positive 12v wire is giving a full 12v when cranking.
not sure if this gonna help I went through this on my 68 CJ. We went from a non original coil back to original and had a problem about cranking/running. We were not getting enough spark. My mechanic used a external resistor with the original coil and it seems to work fine now.

I bet you are not getting enough spark.
