STILL CAN'T FIND TIMING MARKS---->
1956 GMC 302 6-CYL.
ANY INFO WOULD BE HELPFUL.

Timing marks are on the flywheel and are viewable through a small opening in the bellhousing, just above the starter. It will have a pointer in the middle of the opening. You will be looking for a "ball" pressed into the flywheel. Sometimes they are missing, so look for the indentation if it is. GMC's have marks for 5 deg. UC as well as another UC mark......at least the one I had did.
The plate under the distributor with all the marks on it is an "octane" selector........don't let it confuse you. There are NO timing marks on the harmonic balancer, so don't look there.

Also, typing in ALL CAPS IS SHOUTING, so please don't........Thanks

No big deal, though. I have no room to talk; I can't type! :o

If you still can't find it, go underneath and take off the inspetion plate. You can then have a close up look at the flywheel as you turn it around. When you find the ball, clean it up and paint it white. I have found this very handy when using a timing light later.
