Hey Jim, it's great to see you here again! Missed ya!
Thank you for defining the original question. It gets difficult at times when I'm not sure if it's poor grammer or something else! I think you're right.
As far as the advance goes, I just grabbed 34 from memory. As it turns out, we were both wrong. Below is a chart from one my Mitchell manuals (courtesy of Ford). It shows a peak advance of 40 degrees @ 2500 rpm. Disregard the arrow on top, that was for someone else. The lines to check out are the bottom ones. Interesting. I just checked the numbers for the SD 5.0, and that's why I was thinking 34 degrees! Max advance is 34-35 degrees @ 2450 rpm.
As far as this guy running at a fixed 35 degrees, he would be there at 1400 rpms anyway, so I guess it's doable, but I'm not sure why he'd want to. More engine details would help.
Take care,
-Chris
