73 360 Ignition timing after Chain replacement

Gloyale said

The gear set I used only had 3 settings. I am 100% Confident I used the stock keyway notch and corresponding markings.

When I took this engine apart it had a stock Chrysler plastic coated gear set on it, with no adjustments. So there was really no reason to assume the cam was meant to use with anything other than stock markings.

You are making the assumption that the timing set is accurate. It doesn’t have to be, and certainly could be off. By a big margin.

As RRR pointed out above, you don’t have a CLUE where your cam is timed. It’s a wild assed guess at best.

I suggest you pull it back apart and VERIFY where the cam is. If you can’t degree a cam, find someone who can and have them teach you or do it for you.

Until you do that, anything you do or change is just shot in the dark.

If you just refuse to do the obvious, then pull the drivers side rocker cover and out the crank on TDC overlap number 1 and look at the valves. If they are both open the same, the cam straight up. If the intake is open more then the cam is advanced. If the exhaust is open more, the cam is retarded.

That’s better than a guess. The issue becomes how far advanced or retarded the cam may be. You need a degree wheel and dial indicator to verify what you have.
