I heard nothing about the Quality of its running,, only the sloppy timing chain video, which was solved.

My 2 cents...

x2 how is it running?

I do know that the straight 6 engine has a lot of torque due to the long stroke, and massive crankshaft. They're like a tractor motor! It may be that you do have lower than normal compression, and thus lower horsepower (lets say dropped from 190 to 150 or something) but aren't noticing it because those engines are kind of over built and have very decent power. Also, maybe your compression gauge is messed up? Lessee, What kind of oil pressure are you running? Indicative of a worn out engine... Does the pressure drop noticeably after warming up? I understand your puzzlement for sure...
