71 LA 340 timings moved!! how?? looking for help

OK good on the timing light and the non-MSD system.

So to be sure, the timing tape's numbers go 0 on the left end and 60 on the right end on the top? I know it is dumb to ask, but am just making sure the tape is not on backwards....It is hard to catch little things over the internet.

OK, your 98 RON is similar to our 93 octane here. The formulation may still change to make the fuel more volatile in winter... easier to fire off when cold. (Diesel mix changes are a different thing.)
