| My stock damper is marked to, I believe, 30 degrees from the factory. I measured the distance between the marks and added marks up to 40 degrees. I used white rustoleum primer. It has held up surprisingly well - 5 or 6 years now. I've also marked it every 90 degrees for valve adjustments.

| | Al - this method works for me - not for everyone - but - while building the OLDS motors, I got in the habit of permanently marking the dampeners. Saw cut a tiny groove and blackened it. I've added some marks to the bird now too. Measured the OD - multiplied by pi - and calc'd the circumferential distance required to place a mark at the "full advance" timing point. Now - I always "power time" the engine by reving it to high enough rev's to reach full advance and then lock the timing at the top. If you have your set-up right - it will drop right back to the proper initial at idle.

| Thanks for all the replies.
I know I could have done this before I put my engine back in but that would have been to easy!
Luckily it is already marked well enough I can wing it from here.

| Just time it with a vacuum gauge- spend the rest of the time doing important stuff (like playing with the grandkids)...  |
