It may cause some ill effects with the carb operation. I have not heard of anyone replacing the ign and not the Carb too.
I did a search on this recently and there is a ton of info.
Search like this: +HEI and click on the Jeep header on the left. There are mixed feeling about swapping to the GM HEI on this board as you will find out.
