360 out of a 1977 RV

I would suggest advancing it 4 deg then dialing in the dist subsystems in order: initial with vac gauge method/total (initial+slots/no can) to 35 (weld slots or $25 FBO plate) then springs (toss heavy one with elongated loop & sub in a MR gasket or MP light one) then plug in/adj the can (CCW with a 3/32" allen wrench makes it come in slower). An E coil & tossing the ballast is good
