Been studying that page and cross referencing with some other material that I have.

Those EZLs that offer 2 degrees less advance under no vacuum conditions (high load conditions) are for the 2.6 M103 (M103.940). It makes sense when you think about it. With about a 1/4 inch smaller bore, the 2.6 doesn't need as much ignition advance!

Ed, thanks again big time for the info and link!
Regards, Eric
