I can find no timing marks on my crank pulley. When I changed the distributor, I set the timing with a vacuum gauge and for checking accessories or driving around the yard, everything is fine. However, when I hit highway speeds, I'd like to do better than advance it until it pings then back off. Is there an easy to find TDC without disassembling much? Once I mark TDC, marking degrees seems like just a measurement. 57 block with an unknown dual groove pulley. Correct spacing for a Thunderbird, but there are no marks that I have found.



Thanks,

Don
