Ignition timing degrees?

[escobar]

Hey guys, I'm tuning up my '76 AMC 258 i6 / 4.2l , does anyone here know what degrees is the standard for my timing?

It shouldn't make any difference but I'm running a ford ign system with vacuum advance.

Thanks guys.

My 78 is 8.5 degrees at idle. Does the Ford have more advance than the AMC distributor?

Both books I have say 6º BTDC for a '76 with a AMC 258 i6 / 4.2l and a manual Transmission .
