setting ignition timing???

I need some help setting the ignition timing on a 1988 cherokee.

I'm dropping in a new block and using the old distributor. Is there something I need to do to disable the timing advance? The tag/decal on the firewall says the timing is not adjustable so how do I know when it's correct.

I assume that I'll need to find the no.1 cylinder and match the rotor button to the no. 1 plug wire blah blah blah, but beyond that what else do I need to do to get it running and set the timing?

many thanks.

Rob

That's all you'll need to do. The PCM will adjust timing more or less once it starts up.

so then there isn't a base timing that needs to set first, right?

thanks.

No base timing. ECU does it all. You have to be dead on when installing the distributor though. On tooth off will let it run, but it will run really poorly.
