This relates to a Chrysler 318 with electronic distributor and timing marks on the flywheel. There are no degree graduations, just a stationary reference pointer and two marks on the flywheel, one for LH and one for RH rotation.
I'm posting this for a friend who is getting the gambit of how this should be timed. Here are just a few of the directives he was given by several people:
- "2.5 deg BTDC"
- "5 deg BTDC"
- "when the mark on the flywheel is about half inch BTDC"!
- "when the mark on the flywheel lines up with the stationary pointer it is timed properly"
Does anyone know for sure?

My manual says the 2 1/2 setting is for engines up to 1970... 1971 and later are 5 deg BTC.

Thanks for the reply. Anything in there about the marks? Set up the mark on the flywheel 2.5 degrees before the reference pointer (needs advance light), or is it at 2.5 degrees when the 2 marks meet?
I suppose he can set the piston to TDC and see where the marks sit, just thought someone would know offhand.

Sorry wasn't clear..... the marks line up when timing is correct. The age of the engine will have the mark in different position to give 2.5 or 5.
As the engine rpms increase it should get closer to TDC
