There was some discussion, I'm sure, in the past few weeks on the Mopar section about compression not being a big need in these engines.
Or was that on Moparchat forum?
Anyway, someone with some experience reckoned that higher compression didn't necessarily make them better.
I've been looking for exactly what you have for about 30 years, never found one that I could afford (yeah, I am cheap!) that would turn. You are in heaven there.
Quite some differences between the '34 and later blocks, IIRC. And no, no answers to your main question.
