distributor shaft play
Read the shop manual. Checking distributor play is in there, section 8, electrical. You can download many years, free, at MyMopar
I would be checking your TDC mark (use a piston stop) and actually CHECK as to how much advance you are getting.
"Smog" distributors, IE starting in CA in 66 and Federally in 68, and getting worse "by the year" typically have very long, very slow advance curves.
Such things as burning oil aggravates perceived detonation.
