Damper mark @ dot to dot ? ASAP

Just line up the dots on the timing chain first. The cam dot at the bottom and the crank dot at the top to get your timing chain in the proper position.

Then turn it to TDC.

Also, you will not be able to install the mechanical fuel pump in the TDC position as it will be mid stroke of the fuel pump. You must again turn the engine to a position where the fuel pump can be put in place without any "load" from the fuel pump eccentric.

Once you find TDC, if the marks do not line up between the balancer and timing cover marks, then make a mark with white paint or white out to line up with the 0° mark on the timing marks for the timing chain cover. This will get you back to where you need to be if you have mixed and matched parts for early and late small blocks (pre 69 and post 70).
