ISX cam grinds

[in2trux]

All ISX's are not created the same, we've been figuring that out. Is there any information on cam duration, lobe separation angle and lift by CPL?
Whether a 400 hp or 600 hp, the head and block castings are the same, bore X stroke, right?
Valves are the same, are there different grinds for the cams, injectors according to application, CPL and HP? Obviously yes but is there anywhere I can look at it?

The big difference is turbo, CAC cfm, mass air flow and injection metering. Has anybody measured the volume of the different systems, big turbo, small turbo, IH or Paccar?

I'm just trying to sort this out.
