Compression PSI?

No compression release and 80-90 psi on compression is on the low end, not respectable.

No compression release and 80-90 psi on compression is on the low end, not respectable.

The 77 522 21 short block posted by the OP used the 47 010 06 camshaft which includes ACR. So compression release is present
