Lean pop off idle?

I didn't say a single word about whether that cam is; good, bad, or whatever. Nor did I suggest to replace it. All I said was;

and the reason I said that is because of exactly what it is doing in this particular combo, and what it will continue to do.

BTW;
the Wallace Calculator predicts;
at a true 9/1 Scr, cranking cylinder pressure is likely to be ~130psi, which is pretty Low Compression.
At 8.5 this drops to ~120psi which is nearer to Miserably Low.
I don't remember mentioning your name, but as they say a hit dog hollers.Yes, it may be "miserably low" as you say, but can still be tuned to run surprisingly well. Just because you rely on slide rules and calculators and have no real world experience is not "my fault". I'm sure in your world, you pick all the greatest parts to work together better than in anyone else's world, but I'm not impressed. One way of thinking has never fit all. Get over yourself.
