Are you asking what the static compression ratio is on a 0-470? You would need to know exactly what model you have to get an accurate answer and hope that it has never been modified.


Or are asking what the cranking cylinder pressure should be on a healthy 0-470?

I have see GPU's run OK with 70 to 80 psi... But they were down on power and smoked
But idled well and ran ok

A fresh 0470 GPU conversion will have about 150 psi when broke in

This is on a warm motor with hot battery and throttle wide open.
And remember equal numbers are more important every gauge reads
A little different

True AC somebody will chime in but I think true AC will be 140 psi

Good Luck!
