woah
If you were 180* off, would the truck have a really bad idle, have an occasional miss, and a really rich 02 reading?

Re: 180* off?
Well, I got my Ty up and running (if you call it running) after I took the top end off and put in a new cam. I followed the GM service manual to the dime and when I put everything back on it has a really rich reading in DM like about 950mV when idling. It also has an occasional miss when it idles which causes it to stall after a few minmutes of sitting there.
I have double and triple checked the wires to make sure that they are not crossed but I will check them again to make sure.
With the tan wire unplugged I took the left most mark on the dampner to line up with 0* on the timing cover tab.
I have the DM files if it helps in diagnosing what is wrong. Help is more than appreciated.

Re: 180* off?
I am sure you put the timing marks at 6 o'clock (cam sprocket) and 12 o'clock crank sprocket. If you left it there and installed the balancer it would show TDC on the balancer. That is not TDC for #1. It would be TDC for #4. You would need to turn the crank one full rev to be TDC #1.
An easy way to check is to make sure that both the intake and exhaust are completely closed on the #1 cyclinder when the balance is at TDC. After this excerise make sure that your rotor is pointed to the #1 wire on the cap. The rest if the wires will go in order counterclock-wise.
I apologize if this is something that you have down cold and am not wanting to suggest you missed something, but I do notice that sometimes no one speaks up on some of these issues. It's always good to double check. I am always calling someone to double check my work, even on things I have done before. I must be getting old...
