Yeah, I wonder why pinging and coolant temperature are so linked. I know 
combustion chamber surface temps are much higher and change faster than 
the coolant.

I know that engines are overall more efficient at higher coolant temps 
(195/205 than 160 for example) but that goes out the window when you 
have to lose 3 - 6 degrees advance to avoid pinging.

My wagon (70 232, 9.5:1, the squish issue I mentioned) is particularly 
ping/temp sensitive. Not much to do about it now, but believe me, when I 
build the new 232, I will pay attention to it.


I don't understand that much about camming and static vs. dynamic 
compression, but it sounds like it would be worth figuring out soon!
