timing
6 degrees is conservative on timing. Most guys advance the timing to the point max rpm at idle is achieved, and then back off until there is a drop of 50 rpm. Another technique is to set timing, take for drive, and if detonation doesnt occur, advance again, take for a drive, and so on. If you don't have a tach or means of measuring rpm you could do the first method by ear. Other than that try 8-10 degrees advance.
A significant number of Y's have had some deterioration in the rubber component of the balancer, and therefore the timing mark may have shifted.
Edit note: Specs for a 312 in Thunderbird call for 3 degrees with standard tranny and 6 degrees with auto.Last edited by 46yblock; 05-12-2005 at 05:29 PM.
