compression on 1956 7.5 fleetwin

hi was wondering if some one could tell me the compression of this little gem 7520 fleetwin thanks a million

more important cylinders are fairly equal (w/i 10%). Can run OK on lower than expected compression -- what are you getting?

If I remember correctly, around 85 psi. But that isn't written in stone. In fact it isn't even written in the factory service manuals.

I would say 85 is a pretty accurate measured mile.

Most of mine are anywhere from 70 (low end) to the best was about low 90s. 85 about average. As stated, ensure they are equal though. All gauges read a little different.
