Anyone know what kind of pressure I should expect for my readings on a 11 to 1 454? Got an oil consumption problem and suspect broken ring(long sad story http://www.chevelles.com/forum/frown.gif) Thanks for the help.

Pressure dosen't really matter in this case, what you are looking for is consistency, or one cylinder (or more) lower than the others. Could also indicate a bad valve.
Run the test once, record findings. Run it again after squirting oil in for ring checks.
