72 360 first start question
Ok so here's my latest test. I tried Rapid Robert's rockover test and everything seems to be correct.
If I may ask: When you did this test, did you check the intake and exhaust valve retainers on #1 (or #6) with some sort of measuring device like a dial caliper or scale to see that they were open equal amounts, within about 1/64"? If not, then you could be off; you can't do that check just by eyeball and expect good results. If indeed it was done with precision, where was the timing mark on the damper relative to the timing scale on the cover? (You should have taken a reading to the degree.)
Sorry to be so direct; I do want to help. But the point of his check was a shortcut to check cam timing, but if not done carefully, it will not give valid results. Do you have access to a dial caliper or dial indicator? Valve timing can be readily checked with the engine together with a dial indicator. If none, then the timing cover can be taken off as suggested.
As Mopar Tim says, cam timing and ignition timing are different. You can't fix cam timing at the distributor.
But there also seem to be a lot of very basic unanswered questions in this thread..... like vacuum readings, fuel pressure, actual timing, etc. I would suggest you go back and reread such question and answer them. It's impossible to troubleshoot long distance without actual measurements; the questions are being asked for a reason.
