erratic timing on 360

OK ON THE DISTRIB THIS IS THE SECOND TIME i HAVE BEEN THROUGH IT ABSOLUTELY NO ISSUES THAT i AM SEEING AT ALL. OOPS sorry caps. Joe if you want to eliminate electrical send me a list of all the ignition components you are running I can send you know/tested good ones to replace one at a time to try. This is a weird one. I really want to know what it is.
