    Timing Woes.

    Hello everyone, so like the title states I've been having some issues with the mechanical timing side of things. A little bit of back story. I've completely rebuilt the engine, block bored 0.20 over, new pistons, head resurfaced, balance shaft delete (the issue that caused the new rebuild), valve seats cut, valve faces ground, new gaskets all around, new injectors/ regulator, yadda yadda ect ect. So my problem is getting the Cam gear lined up with the nipple on the head (not the top of the head) along with having the distributor lined up with #1 spark plug( I have the body of the distributor marked with paint showing where the nipple is on the cap for #1). The main discrepancy I noticed is that the punch mark on the Cam gear is in-between the teeth on the Cam (I have pictures to show this) unlike it being on a tooth like I've seen in diagrams and everyone else pictures on here. Before I bought the truck the head was resurfaced (have receipts of proof) and has now been resurfaced again when I did my rebuild (so it's been resurfaced twice so far). I'm following the timing procedure correctly, crank is at 0° TDC, Cam gear has been placed on it's punch mark (in-between the teeth), BUT the distributor only lines up with #1 if it is fully advanced, NEVER in its center position nor turned slightly. So I've gone back and set the Cam gear on the tooth below the punch mark and it get slightly closer to #1, but still only lines up well if the distributor is advanced nearly completely (which I know is to much). I know it's non interference so I don't worry much about trying it on either setting but that doesn't solve anything as we know because the distributor is fully advanced which ain't right. The 1st set of pics show the Cam gear on it's punch mark along with the distributor in its center position and with it fully advanced (in that order). Next set of pics show Cam gear on the tooth below the punch mark and distributor in the center and fully advanced ( same order again). Maybe I'm missing something? Any thoughts? Possibly distributor is installed a bit off?
