Default Timing mark ?? (pic)

Hi too all,
Well today is my day, why because after 3.5 years waiting for parts and money and time, my engine is going out of my car. I will put new short block, with rebuild heads, 15g, rps clutch and rps flywheel and some other stuf. I know it is not big deal for most of you, but for me that will be enough for some time, hehe.

Well, first question is, what we notice on my old engine is this timing mark, where crank pully is. Every mark on cam gears ar fine, just down here there is one tooth off. Also in my manuals this is picturise the same, but in mechanikal autodata, he has different. So when we will be putting back my new engine, how should it be done. this whay or another.

And the car is dodge stealth tt 1992
Here is pic (lil big but you can more precisly see)

Edit: What Drweldin said below. Misread picture at first.

Congrats on getting the car back. I'll be going down the same road as you very soon...aside from the whole 3.5 years thing, more like 3.5 months is what i'm shooting for

Assuming your cams are all lined up, you are off (2) teeth on the crank...Edit: more like (1) tooth.
I'd fix that, lol.
Here you go....these (2) should line up:

I can tell from the pictures that your block is a 4 bolt main because of the style of oil pump you have. I can also tell that the timing belt pulley on the crank is for a 91 -92 2 bolt main block. In this case the crank sprocket will be off one tooth when the cam gears are lined up and cylinder #1 is at TDC. This is because they moved the timing mark on the 4 bolt blocks since it wouldn't fit in the original spot. This also means that the plastic timing cover is different between the two engines and you should make sure you have the right one. from what I can tell your timing may be on but you need to verify it. Here are a couple of links you should read to make sure you do this right. Also it looks like you are using the 2 bolt heads with the cam angle sensor on the passenger side of the engine by the throttle body. There is no problem with this and it will work fine. Your crank sprocket will definitely be off a tooth when this is timed properly. I just noticed that this is your old engine. My explanation should cover why the crank timing mark is off and it ran fine. Feel free to ask more questions if none of this makes sense. Good luck.

Believe it or not those two pictures from the manual are trying to show you the same thing.
You want to align the small notch on the back flange of the crank gear that Drweldin highlighted in his picture with the mark on the oil pump. These is no meaningful mark on the front face of the '91-'92 crank gear, and you do NOT align it to the roll pin.
I have the same drawings in my manual. It is hard to see what they are pointing at but if you look with a magnifying glass you can see that they are pointing to the notch.
That first drawing does not show the gear lined up, it is the illustration that goes with the instruction "Shift the timing mark of the crankshaft sprocket one teeth (sic) in counterclockwise direction to facilitate belt installation". In other words that drawing is off by one tooth.
One possible reason that your timing is off on the old motor is that you have to rotate the engine a couple of turns clockwise to set the tensioner. Try rotating it around, always going clockwise, and see if it aligns better.
Another thing to consider is that things changed in '93. If your new motor is a '93 or newer it will be a bit different than the old one. Also, if your Alldata manual is for a latter year it will show the new set-up.

He has a 93 plus block with the 91-92 crank timing sprocket. Read my post and it should be clear.

Yeah, I was still typing when you posted that. Your explanation makes sense and I think you solved the mystery of why the old motor appears off. Are my comments about the drawings correct though?
