Nice increase but that timing change is really curious. I have always ended up
around 36-38 degrees total on B motors....even before we had low compression.
Of course, in the old days I was reading the compression ratio in a brochure or
on a box. I'm not a machinest so maybe I didn't have what I thought I had.
38 degrees total used to be the "majic number" on a stone stock 383 or 440
Magnum. Worked every time.
