I just have a quick question. Can anyone tell me what the PSI numbers should be when running a compression test? I just checked my newly rebuilt 292 today and I'm reading about 120psi on all cylinders and I know that the comp ratio should be somewhere around 8.5:1 on a moderately modified block like mine but I can't find any info on the actual PSI's. Thanks -Tim "Doc"
