1983 LG4 0 BTDC or 6 BTDC base timing

Hi guys, I know the mid 80s LG4s were spec'd at 0 BTDC base timing but someone posted on this board that the 1983 only LG4 was spec'd at 6 BTDC base timing. Can someone else with a 1983 LG4 confirm this? I saw a 1983 caprice LG4 that also had 6 BTDC base timing on the tag under the hood.

I thought 6* was right.... 0* was later for TPI I thought...

that would be the computer controlled distributor done with EST unplugged eh?

yessssssssss I know how to set timing on est setups. I know the mid 80s LG4s were 0 BTDC and the L69s were 6 BTDC. I do believe the 1983 LG4 only had 6 BTDC spec and I'm just trying to verify that.

Yes that is correct. My bro has an 83Z and his stock timing spec is 6 BTDC.
