By chance does the motor have cams? cams with a lot of overlap and aggressive can lower cranking pressure. For instance my motor is 10:1 and with different sets of cams and overlaps I was able to swing compression anywhere from 125-190. What was ring gap and PTW?. My motor is built a lot looser then most but it is built to make a lot of power. Built loose with cams with a lot of overlap could explain it.
