My '68 440 engine has 4 marks on the balancer. When I bought the motor the seller had pulled the distributor. I used my thumb in the #1 spark plug hole and turned the motor to TDC. How am I supposed to know which mark is "the" mark?

it will be the one cut all the way across the damper the others should only be 3/4 ways across use a screw driver to feel the top of the piston and rock it back and forth to get TDC check alinement phase of the itermed shaft slot for dist flat and make sure it points rotor at # 1 term on cap it turns CCW on the dist

if they do go all the way across,then check to make sure #1 has both valves closed and piston at the tdc..use the mark that lines up on 0* mine has the bullet nose damper for cast crank IIRC you have a thin one

Yeah, mine is the thin one. Why would they put all these marks on the balancer? The one on my 383 has only one mark.

magnetic wand for osilascope machine-for timeing/settings goes in the u-shape on the timing tab(on my 78 440)and use the other lines/marks,the balencer can have #s and lines with crankshaft * increments,and may very well have something to do with valve lash the are not stamped very deep in the damper either most times they are painted over and you dont notice them,seen them on a lot of SB dampers usally only one full line is cut across the damper to mark 0*TDC you can referance the throw on the crank by the keyway in the end of crank with damper off,same with cam and doing a t-chain

My freekin' GAWUDWUDEAD!!! Just get or make a POSITIVE STOP and FIND absolutely correct tdc: Remove the ground cable for safety, determine that the piston is down a ways, and put the stop in no1 Gently wrench the engine around, until it stops, then make a temporary mark on the wheel right under the TDC mark on the timing tab. Do the same CCW. Now you'll have two temporary marks some distance apart. True TDC will be halfway between the two, and if any of the marks on the wheel are still accurate, that's where one of them will be.

Not a chance. What you are trying to accomplish, here is that the marks are ACTUALLY ACCURATE. Sticking sticks, screwdrivers, straws, nails, coat hangers, or any other imaginable object in there is a complete waste of time.

I agree, proper use of a mechanical piston stop and then measurement is the ONLY accurate way to determine TDC and confirm the accuracy of the timing marks on the balancer.

No, I am not blueprinting anything. I checked today and there are indeed 4 marks on the balancer and all go all the way across. If you view from the front of the motor starting with the mark furthest left: 1st mark is bolder (slightly wider and deeper) than the other three. Moving right there is about a 1 3/4" space until the next mark. Then about 5/8" to the next and maybe 1" to the last. (those are all guesses) I can get the exact measurements tomorrow if you think that will help. The three that are closest together are all uniformly thinner and less deep grooves. If I had to guess, I'd say the bold line is it. I think the positive stop may be my only answer.
