An old worn out engine (low compression) will tolerate more timing advance. 20* would indeed be a lot even if that were the case, and certainly a lot for 87 octane
Engine was supposedly rebuilt at 250k. It has 285k on it now. Not sure if it's true or not. But engine has been out of the truck at some point. Block was painted blue. Somebody put it together without the block plate between trans and block. Doh. Had long tube headers as well. Air system deleted.
The balancer has a slight wobble to it so I'm assuming it has slipped. I need to replace it
