How much Compression?

I have a virgin '83 460 (75k actual) in an F350 with auto trans. I just checked the compression and have 120 +/- 2.5 psi on all eight cyl. Is this low? What is normal? Virtually no oil consumption between 3000 mi. changes on 10W40.

Don't worry so much about the number as that all the cyl are within about 10% (max) of each other you are within 2% so you are good to go.
