Is it possible for 318 to run with dist. 180 deg. off ???

So if it's a earlier right side la damper on a later left side timing tab, you can time off number
No.

Others might disagree but my timing cover is a 70 up, my damper is 69 down,

With the engine timing set to the passenger side timing tab, there is no cylinder that aligns the driver's side timing tab to the damper.
