Not hard at all.A magneto will cost you more,and deliver less.It will have one set of points,where the standard points system shares the wear between 2 sets of points,both with independent timing adjustment.
Not so easy to correct timing differences with a mag.
There is often little or no advance curve with a mag.With the AAU on the standard points system,you can adjust the advance curve by changing or adjusting springs.You can get full advance at any rpm you like.
Don't use the original '65 AAU and breaker plate.Use the '67 onward AAU (different dwell angle),and a 4CA or 6CA breaker plate.
