electronic ignition want to convert

There are many options for how to do the swap. Each has its benefits and drawbacks. I favor the HEI upgrade .
Just go with the Mopar orange box upgrade kit from Summit racing. Did that with my 65 barracuda and 66 powerwagon. I don't think you will regret it. No problems on my 65 cuda for 20+ years, no problems on my 66 powerwagon. Go for it..
