Well,
not sure if the last post made it... had an attachment I had toconvert to
text...

Yesterday, during cruise at 45 MPH in 3rd gear ~1500 RPM I see about 30
degrees advance.
In OD at 65MPH (1700 RPM) I see between 35 and 40 degrees advance.  At part
throttle accelerating up a hill at 2500 RPM I see about 30 degrees advance
and no knock counts.  
I seem to pick up between 10 and 15 knock counts immediately after a shift
and timing falls to between 10 and 12 degrees then starts climbing back up
again.


Here's what I see at WOT immediately before the shift to 2nd gear:LeSabre

Hopefully this helps or can give an idea of what I'm seeing or where I need
to go...
