New engine - no timing mark
95 f150 4.9 inline six
Just replaced the engine with a rebuild from a local supply place.
Top Dead Center, Stabbed the distributor, set the timing by ear then...no timing mark.
I know the plug wires are correct.
Im certain it was TDC
The timing mark can only be found from underneath.
WTF? Do you think maybe the crank pulley from the previous engine is different. It's keyed so I couldn't put it on wrong.
If they had the cam off a tooth or so would it runs so well? I am stumped.

Is the damper bad? It could have turned and thrown the timing marks off....
Clean the damper really well - there are usually more than 1 set of numbers on it.
Make sure #1 is at TDC on the compression stroke (feel for compression).

Yes they are the same.The timing marks (numbers) on a late model are on a sheet metal plate bolted to the timing gear cover low on the passengers side (which is why it is easier to see from underneath). There is only one damper mark it is a thin scribed line the size of a pencil line and are usually filled with dirt or paint. The correct timing is 10 degrees.

Is damper the same as balancer?

Yes damper = balancer.
The official term is Harmonic Balancer....which balancer do you have on the engine now? The one that came on it from the factory? The balancer itself should have 2 or 3 sets of timing marks on it, ranging from 10*ATDC to 40* BTDC if it's like the ones on my V-8 (should be).
Have you cleaned the balancer? The numbers are imprinted in the balancer and are not very obvious when crud and dirt get in the numbers.
