the only thing i have read about this check is that the lowest reading cylinder needs to be within 75% of the highest reading cylinder.
but there must be some number that would be considered normal for my 351W. before the valve job i had around 150 on the driver side, 5-8. 1-4 had some issues and were well below limits.
after the valve job, i only got 75-95. different gauge than before and the check before the valve job was done with the engine at normal temp. the check after the valve job, i had allowed the engine to cool down a little (first gauge got stuck in the hole!).
anyway, is there a normal number for this engine? someone had suggested there needs to be some minimum compression to create proper combustion of the mixture, and that is why i am asking. thanks-
