Do aftermarket high output Coils have any disadvantages. I have a 74 Duster with Electronic ignition-orange box and Mopar performance Dizzy. If I use a "better" Coil will it actually run better and not cause any issues?
about what compression level, or dynamic compression level would you say a high output coil would be necessary? just a guesstimate for kicksHigher output coils are for use with higher compression engines. As cylinder pressure goes up, it takes more amps to fire the plug. If you have stock or slightly elevated compression, it's really of no benefit to run a high output aftermarket coil.

my motor should be about 190 cranking psi so guess i better start looking into it lol thanks rusty!
But to quote Smokey Yunich; "I think 20,000 volts is actually enough--but what an ignition really needs is a long spark duration--and high amperage."
Enter Capacitor Discharge Ignition.And multi-spark.
The lower resistance coil will increase peak coil current from about 5A to 6.7A, a 33% increase. It is hard to determine, depends on many factors and operating temperature. The peak voltage seen by transistor may also increase at time of discharge, together the transistor sees additional stress. Time will tell.The Coil I was looking at showed .700 ohms and 45,000 volts. To much for system for ECM?
There may be a screw in the top terminal, it might have a o ring seal, it might be loose. Not sure what they are doing these days. A leaking coil is not good.Ok, so I bought a Accell coil. Put it on and car seems to idle a little better. I noticed when I took it out of the box it was a little oily. I hope it was not leaking. I don't know if it was a corrosion protectant oil or not.
