Dick, BBC engines on 98% nitro like 50 or 60 degrees of advance too.

Fact of the matter is, the Chrylser hemis only like around 28 - 35 degrees,
until fuel loads get above 80% Nitro. Once you get up that high in nitro, then
they like 55-70 degrees. When you get that high in nitro, it's my opinion
that you are no longer dealing with flame propogation, etc, you are dealing
with true explisions in the cylinders, and the time of travel of an explosive
charge is much different than a flame burn. But I'm really out of my realm
here, this is engineering stuff. I'm just an old shade tree mechanic.
