I'm about to do a compression test on my 52 Special 263 engine. Does anyone know what kind of readings I should get for an acceptable motor? I know that these were pretty low compression motors to begin with, so I'm not expecting to see any 175 PSI cylinders, but does anyone know what I should be seeing?

Obviously, I'll check out any cylinders that I get drastically different readings on, but I'd kind of like to know what I'm looking for from the get go. Thanks!

Ahhhhh I just answered my own question! I found the tune up link on this site for my car and all the info was there.

To anyone else that may be curious:
140 PSI not to differ more than 10 PSI per cylinder.
