Hello ever one. I'm new to the cougar world. I came across three cougars a couple of months ago, one of them being a 68 GT 390 with a rust free body. The other two I will use for parts.
Now for my question. I just completed a rebuild of the 390 motor and the compression readings are between 150-155 on all the cylinders except #8 which is 125. What do you guys think would be the cause for the lower reading on #8. The motor has not been fired up yet, just cold cranking compression with all plugs out, no carburetor installed.
Thanks for any info/opinions you might have.
