What would be a healthy compression test number for a 50 SC?

Cannot find a good reference for checking compression on the old 50 SC we are working on. Appreciate any help....is 65-70 ballpark?

I just tore down a 1952 case sc I did a compression check before I pulled the head It ran from 90 to 110 PSI It has 35/8 pistons. You may still have original size 31/2 pistons. I can honestly say I have looked also but have never seen factory specification data for compression on an SC. Id be interested as well. Maybe someone will chime in

Anything over 90 would be good, but anything less means the engine needs attention.
