Damper mark @ dot to dot ? ASAP

I like to line up the timing marks on with the timing chain and gears loose. The cam gear mark on the bottom (6 o'clock) and the crank gear on the top (12 o'clock). Then I put them on the engine and turn either the crank or cam until they fit on the keyways, make sure that once you set the marks and gears that they don't (skip a tooth) while you install them. Then double check the marks for 6 o'clock and 12 o'clock once they are installed on the engine.

That is the way that they tell you to install the marks. Then worry about TDC.

Bill Grissom's suggestion is worth looking into, but I have a feeling that if you are using the aluminum water pump, that the old style timing mark bracket may interfere with the outlet for the lower radiator hose (I'm not positive, but it's worth checking out).

As suggested before if you can't use the old style timing mark tab, then either use white paint or timing tape to mark the new TDC location with whatever timing cover that you are using after finding TDC.
