T245 (M37) Compression psi for the 230 CID is:

Compression pressure at cranking speed is 120 - 130 psi. Open throttle wide open when performing this test.

Compression pressure at 1,000 rpm is 150 - 160 psi

Compression will vary if you have a head other than DT as indicated.

100 psi is fine. If you have any cylinders below 90 psi, then I might get concerned and may want to pull the head for inspections.
