Paccar MX-13 tuning

[Running rough]

There are guys out there who somehow think that just because the red moter has a shorter deck height, that it also has a shorter rod as when compared to a c15 cat, even going as far to say as rod ratio sucks in an isx, well I have seen the c15 rod beside the isx rod and they are basicly the same lenght, in fact I would say the isx rod is a bit longer from center of piston pin to center rod journal, not defending the isx just thought people should know,
